We have been given a cat that had a liter of kittens 2 weeks ago. All the kittens died and the mama cat has a wound on her stomach. She is not bleeding, the sore looks clean and she is eating and acting healthy. The previous owner could not afford to take her to the vet and there is not an office open until Tuesday. Is there anything I can do for her here at home until I can get her to the vet?
