Cat Feline Osteosarcoma Prognosis Welfare

Feline osteosarcoma has better prognosis than in dogs, with amputation providing good quality of life for many affected cats.

Key Facts

Feline appendicular osteosarcoma has 50-70% 1-year survival after amputation alone
Chemotherapy adds modest survival benefit compared to amputation alone in cats
Most cats adapt well to tripod ambulation after amputation
Palliative radiation provides pain control as an alternative to surgery
Bone biopsy confirming osteosarcoma is essential before amputation decisions

Welfare Considerations

Feline osteosarcoma prognosis is significantly better than the equivalent canine disease, making treatment decisions more straightforward. Amputation provides good quality of life for most cats with appendicular osteosarcoma, and the relatively good prognosis means treatment is often welfare-justified. Pain management from diagnosis to resolution is non-negotiable.

What You Can Do

Pursue amputation promptly once osteosarcoma is confirmed in an otherwise healthy cat
Manage pain aggressively from diagnosis through the surgical recovery period
Discuss chemotherapy realistically given the modest survival benefit compared to amputation alone
