Hi, I've been looking for more information on something my cat, Luey, does at least once a day. If she is very happy to see me she will run under the chair but where I can see her and lift only her hind legs up and down, like in a dance/marching motion. It is not kneeding, it is like she is stepping with her back legs. I know a lot of cats do the kneading with their front legs and she does this too but the hind leg dance she does is just so cute. I've had cats all my life and she is the first I've noticed doing this. Anyone ever witness a cat do this or know what the meaning behind it is, besides happiness or comfort? Is it very rare behaviour? Any info would be greatly appreciated.
