Any advice would be helpful. here is the situation: Tonya, my spayed 5-1/2 year old cat seems to take extreme offense to the sound of Spooky, my as yet un-spayed 15 month old who has gone back in to heat while i await another Spay voucher. The sound of the caterwauling immediately provokes Tonya to pounce on Spooky or to have a prolonged howl-and-growl which brings out Shadow, my 8 year old spayed girl, who has gone from being the sweetest, most docile kitty in the universe to being a nasty, opportunistic cheap shot artist who turns the situation into a three way brawl (complete with flying fur and copious use of the water pistol from me) by pouncing on whichever of the other two girls is closest to her. I can usually shoo Shadow away if i can persuade her away before a fight breaks out, but Tonya is more insistently hostile at times and i have had to go to some lengths to restrain her so as to minimize the amount of harm she and Spooky will inflict on each other and on my stuff. Meanwhile, when the tensions begin to mount, Spooky's kittens all scatter to safe territory away from the drama (The top of the DVD rack, the top of the kitchen shelf, inside the entertainment center behind the DVD player, in the bath-tub, in a desk drawer)
