I took in a stray cat a few weeks ago and believe she may be pregnant. She has gotten significantly larger and acted like she was in heat when she showed up. I guess I am just wondering what i can do for her to help prepare for this as we have two larger dogs. They all get along fine but one is still a puppy and i want to make sure the kittens will be safe, also i have never been through the birthing process. As i said before she just showed up and as we just bought a car we are limited on the money for a vet for her and im at a loss as to what to do except prepare as best i can. Any advice would be helpful.
