Hello, A month ago I took my roommates cat because he wasn’t good at caring him. He was underweight. But I was feeding him 1k calories of wet food daily. He’s been drinking 4 cups of water a day plus. So took him to the vet. We can’t afford the treatment. I know diet change can help. I’m maxed out with 5 other cats already and I wanted to rehome this cat. I don’t think anyone will take him. I’m not sure what else. He’s sugar was a 4 and he’s kidneys are in good health. He’s 2.5 years. What’s next?
