I have two 4 month old persons that I just adopted. One seems to be drinking more than the other. Should I be concerned? When he drinks he stands at the water bowl for about a minute. They come from great bloodlines with no health issues but it has me concerned. They will be going to the vet to be neutered in about six weeks. I will have blood work done at that time but I was just wanted to know if anybody else has this issue.
