Just dropped him off to be admitted to the emergency vets. Vet says his bladder is blocked, and they have to keep him in a few days.
I understand it's a common thing with male cats, and he's in good hands, but I worry about him. I lost my other cat a couple of months ago, and I don't want to lose him too.
Does anyone else have experience of this problem? I'm not sure what to expect, he's always been healthy (he's 2 in August).
