There has been a feral cat living in my back yard for about 3 months. I have been feeding it and made a warm bed for her to sleep in. She needs to be spayed asap. I have noticed a male cat hanging around the last few days. I have a 3 story cat cage on wheels and managed to catch her in it last night. It has also gotten below freezing at night so it was really best that I caught her. I moved her inside to a quiet room but she hasn't eaten, drank water or used the litter box in 24 hours. Should I be worried? She is so scared. I feel so bad for her. She probably doesn't even know how to use the litter box. How am I going to get her out of the cat cage and into a carrier to get her to the vet? I have never dealt with a feral cat before. I feel like I'm in over my head! Any advice would be greatly appreciated.
