hello! I have a 2 year old cat, Nova, and recently got a 3mo old kitten, Fiur. The integration has gone pretty well, except for playing. Fiur will go after every toy we use, even if I have one in each hand. Nova looks interested, but always lets Fiur go after the toys. We tried a laser, but it made Fiur jump on nova when it wasn't on. She gets pretty irritated when he attacks her when she's trying to play (understandably so!). She seems sad that we aren't playing with her as much, but it isn't for lack of trying! What should I do?
