yeah cats are frickin wierd critters. to make mine purr i usually just have to pick it up, he's a big softie, he got hurt as a kitten, and now has a paw thats fused at a 135 degree angle.. so he's really slow going, like garfield, plus he pushes around our dumb puppy... but to make em purr. . . don't know, , , some you can make purr, others you can't.. oh and some don't like snakes.
