We currently have 2 kitties, Hannah who is a 6.5 yr old, spayed female and Tumbles who is an 18 month old neutered male. We adopted Hannah when she was 7 mos old and Tumbles when he was approx. 12 wks old. Hannah has never been fond of Tumbles and really hasn't wanted him in her house. EVER. Hannah was the top cat until Callie passed away last December. Until her passing Callie was doing an excellent job of teaching Tumbles kitty manners and acting as a buffer between Hannah and Tumbles. Hannah ignored Tumbles and Callie and Tumbles were buds.
When Callie passed away, everything changed, naturally. Hannah was mourning the loss of her companion and Tumbles was asserting his dominance. Tumbles is now the top cat and all he wants to do is play, play, play, and roughhouse. Of course, Hannah is still waiting for him to leave our home and all she wants to do is sleep and play casually. Tumbles tries to interact with Hannah, but all she does is hiss, cry, and scream like he's killing her (which he's not, it's just her warning sound) and run away. We distract him with toys and he has lots of places to run and jump, but I think he is still bored and would like to have a playmate to run around with.
Sooo, what do you all think? Would a playmate help the situation, esp. if we got a kitty of similar age to Tumbles who was more laid-back? Do you have any other suggestions?
Perla cannot stand Wendall. Walden and Wendall came into the home last June and are rescue/abuse cases. They are sweet boys and very docile. In the evening, Wendall will "stalk" Perla. Not aggressively, it is almost like he just want's to tease her - like a boy teasing a girl on the school yard playground... 
. She hisses and screams too. It is very startling. Most times Wendall does nothing to her other than getting too close. I do try to distract him and he does have FIVE other sibling's to play with. But he continues to get a thrill out of teasing Perla. Pipsqueak does what your Callie 
used to do - be the mediator. Pipsqueak will go after Wendall. It just seem's to continue. It bother's me because Perla is my princess and I don't want her upset like this. Thank goodness it is only at night for a few minutes, then it is over. During the day, they are fine. I even have them eating next to each other and they do fine with that. I am not too worried about it. Perla makes a lot more noise than necessary - but it often startles me and I come running.
