He's over 7kg now, 7.3kg in fact. He should be 6kg. I've got a job on my hands to get his weight down.
He needs more cuddles, I think that will relax him a bit about not getting as much as he wants. At the moment he sprays if he doesn't get more when he wants more. It's driving me a bit crazy this behaviour. A few of them are doing it, I think a lot of it is because they need more attention.
