I adopted a kitten at 10 weeks old around two weeks ago and then one week later adopted his Mum too. He's weaned but they warned me he might try to suckle from her and I should make sure he doesn't. I've had them together for not quite a week yet and he does try to suckle from her. When I am with them obviously I stop it but they just both came in to see me and he's obviously had a go at her as she's all wet - I didn't hear a thing, whereas earlier when he tried and I was watching, she lifted him off her by the scruff.
How can I stop him suckling? Do I need to keep them apart?
