This thread is killing me..
My cat just had three little ones, she stayed in heat for so long, and i didnt want to get her fixed that i finaly let her outside for five minutes, came back in and was jumping st8 up and down for like 15 minutes then rolling all over the ground.. ohh yeah she got some ;-))
If you really want to have fun with your cats, tie a sock or a rope around thier waist right where thier back legs are, and watch them.
Its fucks up thier balance and shit, dont worry its not mean, you can take it right off.
