hi all, please help!!!!! i am freaking out here. i just noticed one of my female's (milky's) front paw is swollen. i dont know what to do. It is not irritating her--- she is not limping or licking it. there is nothing stuck in her paw. her nails are fine- not irritated. It doesnt seem to bother her. what could have caused this? what should i do? any input would be greatly apprecitated.
