I have a roommate that called me from work and asked me to come pick this kitten up that a customer brought in and was found in the bushes outside of my roommate job, I need to know what is wrong with the kitten he is not moving at all he is slighty meowing and moaning, he will not eat or drink nothing, he has some type of liqiud come out from his behind please come someone tell me what is wrong or have any idea what is wrong with this kitten the vet here were I live are not going to be open until Tuesday so I need to know if there is anything I can do in the mean time.

Do you have an animal shelter nearby?. that would be your best bet, it sounds like this kitten is very sick indeed and will probably not survive until Tuesday without medical care.
