What could be wrong if my cat will not eat and he is losing weight?

Answer by  Kemaeli (71)

This could mean a few underlying illnesses, for example a cold, they lose their sense of smell therefore they won't eat. It could be simple things like change in their daily routine, a new pet, a new baby, stomach upset, depressed, stressed. It is important to take him to the vet immediately, it could be a more serious illness.

A loss of appetite is often an indicator of sickness or injury. The cat may just be affected by the weather (particularly heat), or a side affect of a medication, but it may also be because of tooth decay, an infection, stress, or trauma.

Maybe your cat does not care for the food you are feeding him, or maybe he is in a new enviroment that is making him feel anxious. Check with your vet to make sure that there is not a severe underlying problem. Good luck to you and your cat.
