Rebecca, I haven't had a leuk kitty being beaten up on, but I did have a pair of siblings who were very, very close, and suddenly Nike started beating up on and chasing off his sister, Nikki. After a few days of it, she wanted to go in another room to get away from him, and I noticed she was drinking lots of water and had lost a little weight. Turned out she was in kidney failure - only 3 yrs. old, and in fact sudden and acute and couldn't be turned around - she died 12 days after diagnosis. It may be they just suddenly want to be bossy, but could be they sense something wrong with Rio. You may want to get him checked just in case.
