My cat isn't eating and seems sick. When should I take him to the vet?

I'm sorry Chloe won't eat! Anorexia is a very general sign of illness, and it could be caused by dental problems, systemic illness, infection, inflammation, or injury. It's actually serious when a cat won't eat, as if they don't eat for 72 hours, they develop a fatty liver which is fatal without treatment. This needs to be avoided, so I would take her into the vet either today or tomorrow. The vet can diagnose what is causing her to not eat, and how best to treat. I hope this helps!

That's concerning! Refusing to eat is often a sign of illness, and without seeing Squid in person, I can't say for sure what is going on. I can also say it can be really serious when a kitten won't eat, as if they go long enough without eating (about 72 hours), they will develop a fatty liver which is fatal without treatment. I'd take him into the vet first thing to take for a health check. I hope this helps!
