All 4 kittens I'm fostering have diaherra from a move change and food change. One has/had blood in his stool. What do I do? I dont know if I can come in this weekend

By appointment only.

They do by appointment only

They are closed on the weekends, and you will need to call them to make an appointment

This happened to my puppy. Was given a dewormer for precautions and diarrhea med. He was fine after. So you may want to contact for referral

I do believe they are closed on the weekends. I would contact them to ask them if they can refer you somewhere.
