Re: Mom cat & her kittens
I was also going to say about 8-9wks old. I think they are at a perfect age to trap and tame/socialize so they could be adopted to their own caring families. The Mamma, well, I think I'd try to TNR her as soon as I could. I began feeding ferals here on our country property and as more and more cats arrived, and I had to put out more and more food, I realized that more kittens from the litters would survive and their mothers would teach them to come to me for food. Eventually, I would reach a financial plateau of what I could afford to feed and then all of the cats would begin to get less/less food, and kittens from litters would not survive and it would go in a cycle of plenty with a high survival rate to less resources and die-off until there were less mouths and more food, then it would begin again.
That is when I began calling TNR and rescue places to help me. Now, I try to TNR every female cat I can catch. Do you have a PetsMart near you? PetsMart is who I foster for and who has helped me with TNR and accepting the kittens/cats I socialize into their adoption program. See if they have someone who could foster the kittens, since it seems your house is already full.
Best of luck,
