My calico regular cat had kittens by a half Manx. He is bob-tailed,as are two of the kittens. the kittens are 3 weeks old and the 2 bobs are dragging their back legs behind them. They can move their legs but they can't seem to move them beneath them when they walk, could this be Manx syndrome?
This sounds like a congenital probelm. If they can not walk with the hind legs then the quality of life for these kittens is very poor. vetcare
