We have 2 loving cats named Socks and Tiger. They both like hanging out and sleeping on my bed. Tiger will sometimes be sleeping on my bed and then Socks will come and try to bite his leg. Tiger meows funny and then they wresle and play. I think so. Is this normal. They are playing. Also why does Socks like to go on top of me and sleep on my legs when I am on the computer or watching tv.
