i wouldn't be scolding him for peeing off the pad. he is a very small baby. and as far as pooping, it sounds like he is doing fine, maybe just getting adjusted and had a tummy ache. Welcome to YT! and don't get too worried, just keep an eye on him and make sure he keeps eating, drinking, and acting normal. it should clear up soon and if it doesnt you should talk to the vet.
also if you changed his food that could be it. |
