About this pet

I’ve had her for a couple of months, she had 3 kittens, we were able to find homes for two and we kept one. She was a stray when we found her, and so she tends to go outside and refuses to come back. She’s starting to fight with her kitten and we have three big dogs. Two of them try to go after her and one day they almost got ahold of her. I’m keeping her kitten but I’m trying to get rid of the mom because I don’t want the dogs hurting her and she keeps running outside and doesn’t let us catch her. She doesn’t get along with other cats, but she gets along with people. She knows how to use the litter box. But she isn’t spayed.
