There is this nice tabby cat up the street that I pass on my way home. He/She is veeeeery friendly and all I have to do is crouch down and go "heeeere puss puss' and he comes running over. He/She does not scratch or bite but loooooves to be petted and scratched, he/she also meowed at me several times in a very cute way lololol. I must have petted that cat for a good five mins! I started to walk away and the cat followed me almost the whole way home!! I know the cat lives in a house just up the street and looks plump and well-cared for. Unfortunately, my dog chases cats so I can't have a cat!! WAAH! I've wanted a cat since I was little but my mom was allergic, grrr.

THE CAT IS VERY NICE PPL, BUT I AM JOKING ABOUT KEEPING IT!
