I have a feral mom with 4 aprox. 9 day old kittens, who were rescued yesterday, and put in my guest room. She is hiding in the closet for 24 hours now, and hasn't touched food or water. How long can she do this for without compromising her health/kittens health? What should I do? It's the weekend and the vets are closed. Please help with advice, as I am very worried about her and the babies. Thanks!
