Our cat has recently changed in his eating habits. For a week or so, he was drinking a lot of water & peeing a lot in his litter box. Now, he doesn't drink in excess, but is still peeing alot. He still eats about the same amount of food, but is losing weight. He is the skinniest he's been in about 5 years. And the right side of his uppper lip is slightly larger than the other side. Any suggestions.
I recommend a visit to a vet so a blood test can be done and your pet can be examined. Your cat may have a thyroid problem or another serious dz. Good luck, vetcare
