I just adopted a kitten, had him a week, so now he is 7 weeks old. I have noticed that when he goes to the bathroom he cries out just before going. When he needs to use the litter he will start crying out and gets in and scratches around a bit then settles in to do his business. He will cry out a couple more times before actually going and then he gets quiet while actually going potty. He doesn't seem to do this when just peeing though. Is this a sign that he has some sort of obstruction? Should he be going to the vet or is this normal kitten behavior, as if to say "leave me alone for a minute while I do my business"?
