Well, the problem is these kits are exactly the same age and circumstances as my dear Tigger (R.I.P.). At 5 weeks, if they don't start interacting with mum or Ron, they'll turn a bit feral, which they are doing already...
And being in the cattery with the others isn't helping. Ron doesn't have the time for 1-2-1 care of these babies to bring them round - he's got 17 other cats, Silver and her babies... and reports of a pregnant mum wandering the area!
I can see I'm just gonna have to go down there, aren't I?
