Have Cat Questions? Ask a Cat Vet Online.
Welcome and thanks for asking your question. My name is***** am a licensed veterinarian. I am currently not set up to make a live call. But, I am happy to answer your question on this thread. First I need to ask you a few questions so that I can be well informed and give you the best advice.
1- How long has this been going on?
2- Is he trying to urinate?
3- Does he cry when you touch his belly?
Friend, I am going to opt out and allow another expert to comment. I don't think I could be of any help in this case without a hands on examination. I am sorry.
