Marmite was the original source of the problem but it's high salt content means I would not give even a small amount now just as I would never give the cats anything sweet beause they never wash their teeth.
I am wondering if she needs some sort of vitamin that is making her so hungry?
The problem is that the more you feed the more distended the belly gets and the hungrier they get. So while it is emotionally very hard to refuse her I have to when I can see by her tummy that she is a little bit more fed than usual.
One thing that makes a cat ravenously hungry is if they eat a mouse or a bird, it seems to have the effect that drinking juice when you are thirsty; the more you drink the thirstier you get.
So I will just give her a few tiny bits of bread 2 square inches in a day, but only if she is really demanding it. I don't give them marge on it because I hear that they cannot digest it. But I womnder if she needs a vitamin that is in wholemeal?
Cats! What a worry
