My boyfriend and I rescued 3 kittens that were too small to eat. We heard them meowing in an old shed , so we got to them and taught them how to lap milk from a bowl and eventually added kitten cat food to the mix. My boyfriend built a cage and put them in until they could care for themselves. Well, they started climbing out the cage so we let them go and by now they could eat cat food. I am not sure how old they were when we found them and their eyes were open but the other eye was matted closed.We assumed the mother had been killed. They were also very small, but anyway I think they might be a little over one one month old are two months old - not sure but somewhere in between. There is also a tom cat that hangs around and he is probably four years old in people years.My question is he has already begun trying to mate with the female kittens that are maybe not even 2 months old. Is this strange or unusual? I have been trying to find a home for the kittens and I cannot afford to have them neutered.
