welcome to animal a day quick Japanese bob chil cat thax the bunny cat they don’t have the normal long and slender cat tails instead their main differentiating feature is their fluffy bunny like tail ball it is caused by a dominant gene so if just one parent was a bobtail most kittens born will be bobtail too the bobtail gene causes pure tail vertebrae to form as well as causing the remaining vertebrae to fuse recent studies say Japan is not their original home they may have been first breed in Korea or China they are good at jumping because of their extra long hind legs compared to other cats
