If you suspect your cat’s water intake has increased or are unsure, a thorough check over by your veterinarian is highly recommended as the sooner a disease is identified, the better the prognosis. Your vet will most likely also recommend some pathology tests requiring a blood and/ or urine sample to help determine the cause of the polydipsia (increased drinking).
A general blood profile can provide information on kidney and liver enzymes, glucose levels and also assess the health of the red and white blood cells. Further blood tests can be run, when indicated, to assess thyroid hormone levels.
A great deal of information can also be obtained from a urine sample from your cat – including the presence of glucose, blood, protein and the concentration of the urine sample. You may be requested to collect a sample from home – not an easy task but achievable if your cat uses a litter tray.
How to collect a urine sample from your cat at home
- Empty your cat’s litter tray of litter
- Clean it with soap and water (no chemicals as they may effect the urine testing)
- Place some non-absorbable litter material such as Catrine crystals or a plastic bag cut up into strips into the clean kitty litter tray
- When your cat urinates, place the urine in a clean glass jar or a urine collection container (you can pick one up from your vet clinic)
- If possible, get the urine sample to the clinic within 1 hour from collection or place it in the fridge and get it to the clinic within 12 hours.
