One of my cats (rescued, approx 2yr old female) has a strange gait. She never seems to walk in a straight line, always has her side facing you when she comes towards you, and sort of twirls from side to side as she does it. When you get close enough she runs off sideways as well! She's been like that ever since we've had her, never mentioned it to the vet as she's not in pain or otherwise acting out of character.
So I don't think this is a medical 'problem' as such, just wanted to know if this is a common thing for cats, as our other cat doesn't do it, previous cat never did, and no other cat I know does either! She is happy and chirrupy, so was just curious to know if this was normal.
