Mom took me back to the Vet yesterday.
This time Mom took me to the vet's office on the other side of town and I fussed at her the whole way there and the whole way back. My temperature was normal and she said everything felt right, but she suggested to my mom that she should do some additional tests. Mom said okay (with a fluttering in her stomach). The vet stole some of my blood, my urine, and my floof! She also gave me some new antibiotics that she said were designed for digestive problems. Mom won't get the results of the tests until Monday and the vet said I should start feeling better in two days.
Mom is really watching me like a hawk. She has put a bowl of water and my stinky goodness in the living room so she can watch my intake. I've been eating really well and drinking my water. I went to the litter box less yesterday than the previous day, but it was still messy.
I am staying close to my mom this weekend. She is giving me lots of scritches and belly rubs.
