Waggle

Our Chaiyya had such a hard time as a little kitten, when she was very ill and got a whole cocktail of antiparasitic and antibiotic medication, she almost died. As a result, she has a condition called ataxia. When she walks, she wobbles a bit, and when she stands on her hind legs, she may fall over.
Perhaps she will get better with time, perhaps not.

Don't worry, Chaiyya doesn't suffer in any way, she is a happy, cheerful, playful little cat. Ataxia cats are called  "Wackelkatzen" in German, so P sometimes calls her Waggle - or Wackel.
