My exercise kitty, Spot, has many strange behaviors but the one that is the most interesting is his reaction to my husband when he gets ready to run. Whenever my husband puts on his running shoes Spot goes crazy.
He will rub around my husband's legs and meow the entire time he is stretching. When T' stretches against the door Spot will usually join him. Spot does not react this way at any other time that my husband works out, only when he is going to go out for a run.
