Hi there, I have a 3 month old kitten only had her 4 days, I went to see her in the room and found what look like vomit. My friend said it's probably a hair ball, it was like a pale brown, it didn't really smell. It was kinka chunky, sorry don't mean to be gross but need to know if I have to bring her to the vet. She's been sleeping the good portion of the day. I tried playing with her and she would not play. Help! Thanks.
