A respiratory infection often invades the inner ear. This throws off the rat's balance, causing his head to tilt to one side. Prompt treatment with antibiotics and steroids can usually reverse the symptoms. If treatment is delayed, the symptoms can progress until the rat walks in a circle or rolls over and over, and permanent damage to the rat's sense of balance can result. A rat with severely impaired balance has trouble eating and drinking and may need to be euthanized.
Any rat you get will likely need vet care eventually, the solution isn't to keep taking them back but to find a good vet. Good luck!singerchic20 said:Thanks so much.
