Kidney lymphoma in a cat

It may interfere with kidney function and can be part of lymphoma affecting other organs. Human lymphoma resources describe related cancer concepts, but tests, medicines and doses for cats are different.

Affected cats may drink or urinate differently, eat less, lose weight, vomit, seem weak or become dehydrated. A veterinarian may feel enlarged or irregular kidneys, but these findings are not unique to lymphoma. Kidney disease, infection and other tumours can produce overlapping changes.

Assessment may include blood and urine tests, ultrasound or other imaging, and sampling cells or tissue when safe and useful. The team may also look beyond the kidneys because knowing where else lymphoma is present can alter the plan.

Ask the veterinarian what evidence confirms lymphoma, how well the kidneys are working and whether other sites are involved. Veterinary chemotherapy is often discussed because lymphoma cells may be distributed through the body. Fluid support, nausea control, nutrition and other symptom care may also be needed.

Give only medicines prescribed for this cat; some human pain medicines can be dangerous to cats, particularly when kidney function is impaired. Keep a daily note of food and water intake, urine output, vomiting, alertness and ease of movement for follow-up visits.

Call the veterinary team promptly if the cat eats much less, vomits repeatedly, produces noticeably less urine, becomes increasingly weak or cannot keep prescribed medicine down. Seek emergency care for collapse, severe breathing difficulty, seizures, inability to urinate, profound unresponsiveness or suspected poisoning. During treatment, follow the clinic's specific instructions for fever, diarrhoea or infection concerns.

Consider asking: Is the diagnosis confirmed by cells or tissue? Are both kidneys affected? What do the blood and urine results show? What is the aim of treatment? How will response and kidney function be checked? Whom should I call if symptoms worsen after medicine?
