OK last night the kitties were playing I HOPE they were chasing each other around the room, I am not sure if they were playing because bella jumped up and i started petting her next thing i know i got two BIG scratches on my hand, so is this just playful aggresion? Theres really no hissing or growling or anything except for this one time last nite when bella was trying to get a treat and the kitten wasnt paying attention adn well stormie jumped on bellas head and that was the only time i heard hissing and i stoped that lol, they were running back and forth chassing each other, jumping on things, looking for each other and scheming, is that normal play? I def have to get their nails clipped though well bellas ecspecially lol if this is normal play, please help me I barely got any sleep last nite because I didnt know if this was normal or not???
