I have 2 cats age 13,in the past few days one of my cats has started drinking alot more water than usual.when I run the faucet he jumps up and starts to drink from it(for a long time) he always has fresh water and he drinks from his bowl also. He seems to also have lost a little weight lately. His brother on the other hand is twice the size but does throw up alot. I have changed their food often and he seems to be not throwing up as much on Iams dry food. But after a few weeks he starts again and I change the food for a few days then go back to Iams. can you help with these two problams? thank you very much.
Your cat needs to be seen by a vet for the problems that you mention. Many different diseases can cause weight loss and increased water intake. vetcare
