This morning we took Lulu to the vet and had her put to sleep. On Friday night we noticed Lulu was leaning over to one side, almost like she had had a stroke. She wasn't getting any better and seemed to be getting worse.
Leah was very sad this morning. Lulu has been part of the family for over two years. Rats only live 2 to 3 years. The vet seemed to think she had a brain tumour and it's quite common in rats.
