Hello I recently adopted a 3 month old Siamese mix kitten 5 days ago. The person I adopted her from told me she was litter box trained and eating on her own. The first day I had her she didn't eat at all and I thought she just needed time to adjust to her new environment. I tried feeding her wet food that she ate a small amount of the second day but noticed she was vomiting. So I asked the original owner what food she was feeding her and went out to buy the same one. I gave her the dry food she was eating before I got her and she still does not want to eat or drink water. She is also urinating on my floor and hasn't had a bowel movement since I brought her home. She does not seem sick at all, she is very playful and vocal. I am confused what the problem may be? I also tried mixing kitten replacement milk in her food to entice her to eat but with no success. She is 3 months old so she shouldn't have a problem eating and using the bathroom on her own so are there any suggestions I should try before taking her to the vet?
