🔍 Understanding Polydipsia

Polydipsia, or excessive thirst, is defined in cats as drinking more than 100 ml/kg/day (~1.5 oz per pound) :contentReference[oaicite:3]{index=3}. While cats normally drink between 30–70 ml/kg/day, consuming beyond this range is a clear sign to investigate further.

👀 Reasons Your Cat Might Drink More

• Dietary changes: Cats eating primarily dry food drink more compared to those on wet food :contentReference[oaicite:4]{index=4}.
• Heat & activity: Hot weather or increased exercise raises fluid needs :contentReference[oaicite:5]{index=5}.
• Environmental factors: Cats dislike dirty water bowls or bowls near food—it may discourage drinking :contentReference[oaicite:6]{index=6}. Using fountains or multiple clean bowls is helpful :contentReference[oaicite:7]{index=7}.
• Dehydration recovery: Occurs when recovering from vomiting or diarrhea :contentReference[oaicite:8]{index=8}.
• Medical conditions:
  • Chronic kidney disease (CKD)—most common in older cats, causes dilute urine and thirst :contentReference[oaicite:9]{index=9}.
  • Diabetes mellitus—high blood sugar triggers thirst and urination; watch for weight loss and increased appetite :contentReference[oaicite:10]{index=10}.
  • Hyperthyroidism—common endocrine disorder causing weight loss, hyperactivity, and excessive drinking :contentReference[oaicite:11]{index=11}.
  • Liver disease, hypercalcemia, or Cushing's disease—may also cause concurrent drinking :contentReference[oaicite:12]{index=12}.
  • Psychogenic (behavioral) polydipsia—rare, often stress-related :contentReference[oaicite:13]{index=13}.

🚨 Red Flags That Warrant Vet Visit

• Thirst > 100 ml/kg/day or noticeable increase in water intake :contentReference[oaicite:14]{index=14}
• Increased urination—litter box wet more often or needing more cleaning
• Weight loss, increased hunger or lethargy—suggesting diabetes or thyroid issues
• Vomiting, diarrhea, or dry gums—signs of underlying illness or dehydration
• Frequent drinking from unusual sources like taps or toilets

🔬 Veterinary Diagnostics Guide

1. History & physical exam: hydration, weight, palpation
2. Routine bloodwork: CBC, chemistry panel, thyroid levels, electrolytes, and SDMA :contentReference[oaicite:15]{index=15}
3. Urinalysis & urine specific gravity: evaluates concentration and filters for glucose, proteins :contentReference[oaicite:16]{index=16}
4. Urine culture: if urinary tract infection suspected
5. Imaging: abdominal ultrasound, possibly chest X‑ray—for organ assessment
6. Specialist tests: endocrine testing (insulin glucose curves, thyroid scintigraphy) or hormone assays as indicated :contentReference[oaicite:17]{index=17}

💊 Treatments by Underlying Cause

Chronic Kidney Disease

• Prescription renal diets, phosphate binders
• Subcutaneous fluids at home or in clinic for moderate cases
• Monitor blood pressure and SDMA regularly

Diabetes Mellitus

• Insulin therapy + low carbohydrate wet diet
• Home glucose monitoring and routine vet check‑ups

Hyperthyroidism

• Antithyroid medications, radioiodine therapy, or surgery
• Monitor kidney values—thyroid treatment can affect renal function :contentReference[oaicite:18]{index=18}

Other Conditions

• Treat liver disease, hypercalcemia, or hormone imbalances as diagnosed
• Behavioral cases may benefit from environmental enrichment and stress reduction

🏠 Home Hydration & Support

• Offer multiple clean water sources—bowls of ceramic or stainless steel in cool, quiet spots :contentReference[oaicite:19]{index=19}
• Provide a running fountain—many cats prefer it :contentReference[oaicite:20]{index=20}
• Switch to wet food or add broth to boost fluid intake
• Monitor water intake and share logs via Ask A Vet app
• Encourage play to stimulate appetite and hydration
• Ensure fresh water daily; wash bowls to avoid odor

📋 Case Study: “Bella” with Early Diabetes

Presentation: 8-yr-old, polyphagia, weight loss, polydipsia & polyuria
Diagnostics: Blood sugar high, glucosuria, low urine concentration
Treatment: Initiated insulin + wet diet, fluid monitoring tools
Outcome: Drinking normalized within a week; stabilized weight & energy

🛡️ Monitoring & Prevention

• Annual wellness exams with blood & urine testing
• Feed wet or moisture‑rich diets
• Track bowl levels daily and message changes via Ask A Vet app
• Use teasers or scheduled feedings to encourage drinking habits
• Manage chronic conditions like CKD or thyroid early
