I wish I could quote you all and reply to you all individually. I honestly didn't expect to even get half the amount of supportive posts as I have done. Thank you
so to everyone that posted, (and the ones that messaged me privately), and offered kind words and understanding.
Okay, so spaying... would this make any difference? Would the aggressive tendencies already be set in too much for spaying now to make a difference? Truthfully, spaying Gypsy really scares me because of the CT issue. She's the instigator though. Kayla is so placid and just wants to love all the time, except for when she's snapping at Amelia that is obviously.
Like just now for example when I was replying to some of the posts... Kayla was laying in her basket on the other side of the room and Gypsy was on the back of the sofa. Both were laying quietly. Suddenly Gypsy stands up, eyes fixed on Kayla and growling at her.

Kayla just looks up at her and then puts her head back down and goes back to sleep. Then I tell Gypsy "No" and she lays down again. I just don't get it.

I want to try what Mike's email said, along with a visit to the vet like Rose suggested and go from there. It's like a waiting game though. I'm constantly on edge for a fight breaking out and it's really not fair on me, Amelia or either of the girls.
