Hello! It sounds as though being stimulated to pee is suddenly painful or uncomfortable for your tiny one. It could be purely behavioural - some kittens take over urinating for themselves at this age - but it's important to know that your kitten can urinate by himself. Definitely give him lots to drink, but an emergency vet-check up sounds to be a very good idea if you think that he may be unable to urinate so that they can check that the bladder is not too full (often, the journey to the vets stimulates a wee and if not, he is in the right place).
