Ok so when we got up this morning we noticed that Izzy wasnt looking good, and we thought well maybe she was just hungry. Well we set down some food and thought she would eat, well her sister ate but she didn't. Anyways later this morning she as in Izzy threw up about 5 times and had the runs once. I don't think she got into anything last night, their X pen is tall and there isnt anything around them really. Now she has been sleeping kinda underneath a dresser. Do you think I should take her in to the vet? We have an appointment tomorrow for the remainder of their shots and what not, so I would like to see tomorrow to take them in. But if I have to I will take them in today.....so what do you think??
