My kitten is 3 months outmoded and her vertebrae legs shake when she is lay down...?
Does anyone know if this is something wrong...? Thanks!
Theres nothing wrong with her, It means shes sunny.
Sometimes these are involuntary spams as they fall asleep and sometimes it is them just fooling around and have a good time. A 3 month old is generally too childish to have nerve damage so I would pretty much rule that out unless she is walking strange as all right. If her walking, running and jumping appear normal, I don't believe it is anything to worry in the order of.
Answers: She's probably fine, but if you are concerned or it gets worse I would bear her to the vet.
good luck!
