Hi, As for his not being bullied because of his size. He does not know
what size he is. The bully in my household is the smallest one. You may
want to kill me for saying the following; Due to his spraying you have
had to continue to bring new things into your home. This could be
"adding gasoline to the fire". Some cats cats can become very upset when
any thing new is brought into their area. This is a natural reflex. With
some cats this signals "Danger" Something has changed in their den. I
use to have a cat like this and anything new, even a picture on the wall
could upset him. This was a very loving cat. My vet did tell me tho that
"Little Red" due to his natural reflex, was the closest thing to the
wild he had ever seen. May I suggest that when you come home from the
grocery store lock him up until everything is put away.
