Why is my cat throwing up undigested food and losing fur on its ears?

Updated On September 23rd, 2025

Pet's info: Cat | Bombay | Male

my cat was wild and we have tamed it. this morning it vomited. it just looked like the food had come back up undigested, and milky. we fed it cat food and milk-it wouldnt take anything else-and is a fast eater. we think it may have been eating too fast. it is acting like normal and is waiting outside the front door for more food. it also has weird bumps in its ears and the fur on its ears are falling off. it shakes its head occasionally and quite often itches them. otherwise it seems to be healt

I agree, it sounds like DJ is eating too fast when he first comes inside. You can try a cat feeding toy or slow-down bowl to get him to eat slower (see link below). After cats are 6-8 weeks old, they no longer need milk. Milk can actually cause GI upset, so I would discontinue the milk. Cat food and water is just fine. I would have DJ evaluated by a vet for ear mites, ear infection, allergies, ringworm, fleas, or bacterial infection that could be causing his head shaking and hair loss.
