Hm well if they at least get along for the most part then that good, I mean they could fight all day long and be hurting each other. Ohh jealous cats aren't fun, my cats (both inside, both castrated) get along fine, they love each other, but my bigger cat (in fact a female) gets jealous when I'm cooing/talking to my other one (male), but other then that it's okay. Haha your dog is just used to cats altogether and that really good. He could be barking and stuff all the time at them.
Oh he passed away that's sad :( Well if he and Raja got along so great then he could be still mouring
And don't worry about the long comment, mine isn't any better xD
pretty good.
