FAQ: Would My Cat Gain Weight if She Had Cancer?

by | Aug 24, 2021

Answered by Dr. Jeff Feinman

It depends on how they’re gaining weight. Sometimes, cats with cancer will develop a form of malnutrition called cachexia where they appear to be gaining weight and their bellies get bigger but their muscle mass along their back is thinner and thinner.  In that case, they may be gaining weight as the result of a tumor or fluid in the belly while they’re losing muscle mass. 

The best way to reduce your pets’ risk from cancer and differentiate weight gain from cachexia cancer and other symptoms is to bring them to the vet to have a veterinary exam and they will decide.
