Spaying helps big time... Kirby F3 would bite and scratch everytime I got close to her. After she got fixed, I can pick her up and wrap her around my neck. Of course an F1 is a whole lot of monster.. My F1 didn't respond to clicker training, but prefer the hot dog treats like a dog. So I started to train him like a dog owner would train. It became alot easier.. I've notice with alot of the F1 owners, they allow the F1 to be the alpha in the house.. big mistake.. even if you say you are the alpha, the F1 will laugh at you.. I've been bitten and scratched by my F1 through the years, but I never gave up on trying to be on top.. Here's a true test of who is alpha... Chicken wing.. Hand it to Kenya, if she pulls first, she is alpha... My F1 will not pull or growl with a chicken wing.. He won't lick it, but will stare.. until I set it on the floor, and take a step back.. Then he will eat it. I can come up to him and take it away without a growl... I'm the aplha male according to to my SV.. my wife is the alpha in the family.
It took a lot of training, but we all managed to get along.. that includes the way she trained me..jk
