Cat Lymphoma: Welfare Throughout Diagnosis and Treatment

Lymphoma is one of the most common cancers in cats, and navigating diagnosis, chemotherapy, and end-of-life care requires careful attention to feline welfare and quality of life.

Key Facts

Lymphoma is the most common feline cancer, accounting for 50-90% of all haematopoietic tumours in cats
Small cell (low grade) alimentary lymphoma has a median survival of 2+ years with treatment; large cell lymphoma has much shorter survival
The COP protocol (cyclophosphamide, vincristine, prednisolone) is commonly used for high-grade feline lymphoma
Cats on chemotherapy often experience nausea, reduced appetite, and lethargy, affecting welfare
The feline hiding behaviour means illness is often masked until welfare is significantly compromised
Quality of life assessment in cats with cancer requires owner-completed tools as cats rarely show overt pain
Steroid (prednisolone) therapy can maintain quality of life in cats unsuitable for full chemotherapy

Welfare Considerations

Feline lymphoma management requires ongoing welfare assessment throughout treatment. Cats are masters of concealing discomfort, making systematic quality of life monitoring essential rather than relying on obvious pain signs. Treatment decisions should account for the cat's tolerance for veterinary procedures, travel stress, and medication administration at home. For many cats, a good quality of life maintained for a shorter time may be preferable to aggressive treatment with significant side effects.

What You Can Do

Use a validated feline quality of life scale such as the Feline Quality of Life Scale throughout treatment
Ask your vet about appetite stimulants and anti-nausea medications to support welfare during chemotherapy
Create a stress-minimised home environment with hiding places and calm feeding routines
Consider whether home-based treatment options minimise clinic stress for your cat
Begin end-of-life planning early to ensure you can make calm, welfare-focused decisions
