What is going on?

Ok so our cat Ash had kittens about about 2 and a half weeks ago and our other cat Pickles is acting concerned about them, we also think she may be pregnant, any ideas?

I wouldn't let any other cats around the babies until they're a little older. Have you considered getting the other cat fixed? If she's not too far along that might be the best option. Especially since you already have one litter to find homes for. 2 litters will be more time, energy and money.

If you don't get her fixed, I would seperate them and give each one her own space.

Thank you, but what's odd is that she usually hates other cats and she is around 5-6 when she is in there (5-6 depending if the mother is there) and even let's them climb all over her. She also let's the mother lick her.

We also think she is about 5-6 weeks along in pregnancy.
