Dehydration: A Common Cause of Appetite and Nose Changes
Dehydration tops the list of reasons for appetite loss and nasal dryness in cats. Like all living creatures, cats need water to survive.
When a cat doesn’t take in enough fluids, dehydration results. The body pulls water from tissues, causing potentially serious complications:
- Dry mouth, gums, eyes, and nose
- Loss of skin elasticity
- Rapid heart rate
- Reduced urination
- Higher body temperature
- Lethargy, weakness, and collapse
Severe dehydration can damage major organs like the kidneys and brain. It requires emergency fluid therapy to correct.
To avoid dehydration:
- Ensure fresh, clean water is always available. Cats prefer wide, shallow bowls. Place bowls in multiple locations.
- Feed wet food to boost moisture intake. Canned or pouched food has high water content.
- Add extra water to dry food. Mix in broths or water to rehydrate kibble.
- Encourage drinking with fountains. Cats enjoy moving water. Filters keep it clean.
- Serve food at room temperature. Cold food from the fridge suppresses thirst signals.
Monitor your cat’s water consumption. Notice lapses early and take steps to increase hydration. Dehydration sneaks up quickly in cats and makes them feel crummy.
Appetite Loss and Nose Dryness Signal Disease
While dehydration commonly causes appetite issues and nasal dryness, more serious illnesses can also present this way. Any ongoing decrease in food intake plus parched nose points to health problems in cats.
Get prompt veterinary attention for reduced eating and dry nose lasting over 24 hours. The following disorders frequently produce these symptoms:
- Gingivitis and tooth abscesses cause oral pain. Chewing and eating become difficult.
- Bad breath, drooling, and loose teeth indicate dental disease.
- Treatment involves professional cleaning, extractions, antibiotics, and pain medication.
- Prevent gum inflammation with annual cleanings and daily tooth brushing.
- Damaged kidneys cannot concentrate urine, causing increased thirst and urination.
- Appetite declines due to metallic mouth taste, nausea, and ulcers.
- Bloodwork, urinalysis, imaging, and biopsy diagnose kidney issues.
- IV fluids, diet changes, medications, and dialysis help manage kidney failure.
- Annual senior screens catch kidney disease early when treatment is most effective.
- Elevated blood sugar leads to excess thirst and urination.
- Weight loss despite increased appetite is a clue. Vomiting, lethargy, and ketoacidosis may occur.
- Diagnostic bloodwork shows high glucose levels.
- Insulin therapy, dietary changes, and weight control successfully manage diabetes.
- Obese and senior cats are at increased risk for developing diabetes.
- An overactive thyroid gland drives increased metabolism.
- Cats drink and urinate excessively but still lose weight. Vomiting often occurs.
- Vets diagnose hyperthyroidism from physical exam, bloodwork, and imaging.
- Treatment options include medication, radioactive iodine, diet change, or surgery.
- Gradual thyroid enlargement mainly affects middle-aged and older cats.
- Feline cancers, especially lymphoma, squamous cell carcinoma, and mammary tumors suppress appetite.
- Enlarged lymph nodes, oral masses, and abnormal lumps signal cancer.
- Definitive biopsy is needed for diagnosis. Staging determines treatment.
- Options include surgery, chemotherapy, radiation, and palliative care for quality of life.
- Lean cats over age 6 are at increased risk. Self-exams find tumors early.
- Nausea, vomiting, diarrhea, constipation, gas, and cramps make cats not want to eat.
- Parasites, foreign bodies, inflammatory bowel disease, and other GI issues cause symptoms.
- Diagnostic approaches involve labwork, fecal tests, biopsy, endoscopy, and imaging.
- Treatment depends on the specific problem identified. May include diet change, medications, supplements, or surgery.
- Feed high-quality food and avoid dairy, carbs, and junk food to support good GI health.
- Bacterial, viral, and fungal infections often reduce appetite.
- Localized infections like abscessed wounds, URI’s, and bladder infections or systemic illness like FeLV, FIV, FIP may be present.
- Cultures, bloodwork, and imaging help identify the organism and locate infections.
- Antibiotics, antifungals, fluids, pain control, and wound care treat infections.
- Keep cats current on vaccines and promptly treat any illness to thwart infections.
Less common disorders like heart disease, arthritis, neurological conditions, and more may also depress appetite and lead to dehydration through increased panting, vomiting, or metabolic changes.
Comprehensive vet care identifies any underlying disease causing decreased food intake and dry nose. Bloodwork, urinalysis, imaging, biopsy, and special testing pinpoint the diagnosis. Treatment corrects the specific problem.
Tips to Tempt Your Cat’s Appetite
Seeing your cat turn up their nose at their usual favorite foods adds insult to injury when they are already not feeling well with a dry nose. While fixing the underlying cause is key, you can coax your kitty to eat more in the meantime with these tips:
- Try tempting foods like tuna, chicken, beef broth, salmon, cheese, or cat milk. The smellier the better!
- Warm food to body temperature to increase aroma and taste.
- Hand feed special treats and rub food on your cat’s face to stimulate appetite.
- Soften dry food with warm water or broth to make it easier to eat.
- Elevate food bowls to make eating more comfortable.
- Add churu puree or nutritional gel supplements to boost calories.
- Consider appetite stimulant medications from your vet.
Do not abruptly switch your cat’s diet while they are ill as this may further upset their stomach. Gradually transition back to their regular food once their appetite fully returns.
Pay attention to how much your cat is eating and drinking each day. Track appetites changes. Contact your vet if poor intake lasts over 48 hours to avoid dangerous complications.
When to See the Vet
Get veterinary attention promptly at the first signs of appetite decrease and nasal dryness in your cat. Timely treatment is critical, as cats can deteriorate quickly.
In particular, seek help right away if your cat shows these more serious symptoms:
- No interest in food for over 24 hours
- Little to no urination in past 24 hours
- Dry gums or skin tenting (slower return when pinched)
- Weakness, wheezing, trouble standing or walking
- Crying out or hissing from pain when touched
- Weight loss greater than 2-3% body weight
- Confusion, disorientation, wobbly gait, or seizures
- Marked lethargy, vomiting, diarrhea lasting over 12 hours
Emergency care is called for if your cat collapses, has seizures, can’t lift their head, or is nonresponsive. Dehydration can become life-threatening quickly, so don’t delay getting help.
Diagnostic Testing for Cause
To determine what is causing your cat’s dry nose, lack of appetite, and any other symptoms, your vet will recommend diagnostic testing.
Initial standard tests usually include:
- Complete blood count (CBC) – Checks for anemia, inflammation, infection, and organ issues.
- Biochemistry panel – Measures kidney, liver, pancreas, electrolyte, and protein levels.
- Urinalysis – Analyzes concentration, blood, crystals, bacteria, and cellular debris in urine.
- Total T4 – Screens thyroid hormone levels for hyperthyroidism.
- Feline leukemia (FeLV) and feline immunodeficiency virus (FIV) tests – Checks for these common cat viruses.
Based on initial results, your vet may advise:
- Cultures – Identify bacterial or fungal infections.
- Feline pancreatic lipase immunoreactivity (fPLI) test – Diagnose pancreatitis.
- Abdominal ultrasound or radiographs – View gastrointestinal tract, liver, kidneys, and tumors.
- Dental examination and skull radiographs – Evaluate tooth and jaw health.
- Biopsy – Take tissue samples to diagnose cancer, FIP, intestinal disease.
- Blood glucose curve – Monitor glucose over 12 hours to diagnose diabetes.
Let your vet know about any appetite or behavior changes, weight loss, unusual symptoms, injuries, or possible toxin exposure in your cat. This information helps determine which tests are needed.
Possible Treatments Based on Diagnosis
The exact treatment for a cat refusing food with a dry nose depends on the specific cause determined through diagnostic testing. Some common treatments by condition include:
- Subcutaneous, intravenous, or intraperitoneal fluid therapy
- Hospitalization on IV fluids and monitoring
- Antiemetic injections if vomiting
- Syringe or assist feeding
- Ongoing increased water intake at home
- Tooth extractions
- Oral surgery for root removal, biopsy
- Antibiotics and anti-inflammatory medication
- Soft foods during recovery
- Annual dental cleanings
- Intravenous or subcutaneous fluids
- Medications – ACE inhibitors, phosphorus binders, antacids
- Prescription kidney diet
- Blood pressure medication
- Monitoring and modification of treatment as disease progresses
- Once or twice daily insulin injections
- Urine glucose monitoring
- High protein, low carbohydrate diet
- Consistent meal timing coordinated with insulin
- Exercise and weight loss as needed
- Oral medication to lower thyroid hormone
- Radioactive iodine injection to destroy thyroid nodules
- Surgical thyroidectomy if isolated mass
- Switch to thyroid diet once stable
- Repeat bloodwork to monitor results
- Anti-nausea medications
- Prokinetic agents to improve motility
- Special diet such as hydrolyzed protein or high fiber
- Probiotics and electrolyte supplementation
- Fluid therapy and nutritional support
- Surgery, chemotherapy, radiation treatment
- Pain medications, steroid therapy
- Nutritional supplements and feeding tubes
- Palliative and hospice care
- Appropriate antibiotics, antifungals, or antivirals
- Wound care and draining of abscesses
- Intravenous fluids if dehydrated
- Nutritional support until infection resolves
- Strict hygiene protocols for contagious diseases
With supportive care from your vet and proper treatment for the underlying cause, your cat’s appetite should return to normal along with regaining a moist, cool nose.
Supportive Nutritional Care
Nutrition plays a key role in recovery when your cat has a decreased appetite and dry nose. Follow these tips to support your kitty through illness:
- Initiate assist feeding if needed – Syringe feed recovery foods or blend your cat’s meals into “smoothies” until they can eat on their own.
- Choose highly palatable prescription diets – Veterinary therapeutic foods address kidney disease, cancer, gastrointestinal issues, and more. Cats love the taste.
- Supplement with nutritional gels – Products like Nutri-Cal provide concentrated calories plus vitamins missing from poor intake. They come in appetizing soft gel formats.
- Ask about appetite stimulants – Drugs like mirtazapine help spark appetite while treating nausea, vomiting, and GI problems.
- Weigh regularly – Track any weight loss greater than 2-3% of body weight and report it, as adjustments may be needed.
- Consider a feeding tube – For cats not eating at all, temporary nasogastric or esophagostomy tubes deliver nutrition directly to the stomach or esophagus.
Support recovery with palatable, calorically dense foods to prevent malnutrition during illness.
Proper nutrition ensures your cat’s body has the energy and protein to heal itself following whatever diagnosis impaired their appetite and led to dehydration. Your cat will regain strength faster with assist feeding and high quality therapeutic diets.
Prevention Is the Best Medicine
While occasional appetite variances are normal, ongoing lack of eating coupled with a dry nose requires prompt veterinary diagnosis. To help prevent future instances:
- Keep up annual exams and labwork – Catch issues early before cats stop eating.
- Follow dental care routines – Daily teeth brushing and professional cleanings avoid dental disease.
- Feed quality nutrition – Pick foods with optimal protein, calories, and moisture for your cat’s age and health status.
- Recognize changes quickly – Note and address any decreased appetite, lethargy, weight loss, or thirst changes right away.
- Reduce stressors – Limit changes and maintain consistent routines. Make diet changes gradually.
- Provide stimulating play – Exercise and interaction help keep cats active and engaged.
- Administer preventative medication if needed – Chronic kidney disease, hyperthyroidism, diabetes, and GI issues benefit from early treatment in senior cats.
By identifying and managing health problems early through proactive veterinary care, you can help your aging cat avoid appetite decline and associated dehydration. Keep kitty eating happily with their familiar moist pink nose for many years to come.
The Takeaway: Call the Vet at First Signs
If your cat’s nose is persistently dry and their appetite poor, don’t delay. Contact your veterinarian right away for an exam. Prompt diagnosis and treatment are vital. With supportive care guided by your vet, your feline companion should be feeling like themselves again soon.
