We have some crazy animal management going on in my house right now.
It all began 8 1/2 years ago when I picked up a darling Jack Russell Terrier pup. She is a very good girl. Terrier through and through but listens well. Her name is Abby.
We decided to breed Abby. We allowed 2 litters then had her spayed. We kept a puppy from the final litter. Because of the nature of JRT's we were advised to keep a male pup as 2 males, or 2 females will not get along.

Yeah, right. Didn't work this time.
Moose, (who happened to be the biggest of the litter, and the piggiest little eater, and had more gumption than any of the other puppies) turned out to be a bad, bad boy. He DOES NOT play well with others. He turned out to be a highly dominant dog and Abby is not aggressive but she won't back away from Moose either.
So, we have taken to having to feed them individually so they don't kill each other while eating, even when they have separate bowls. So, one goes downstairs while the other eats. Also, no toys allowed with the exception of an old rope bone and some tennis balls. All other toys are cause for a war.
I've always liked cats. Abby is good with cats and other animals. Moose is not. So, we have been unable to get a cat.
HOWEVER, 3 weeks ago, when the weather was really crummy, the cutest little cat showed up on our front steps. A beautiful, sweet, little tortoiseshell/calico about 6 months old and the friendliest little thing ever.
I felt so sorry for her outside I did a big no-no. I locked the dogs downstairs and brought her into the house. I
fed her. Now when she's outside and wants in the house she hangs on the screen of the back door and drives the dogs crazy.
She is now our indoor/outdoor cat, but mostly indoor. She sleeps in the house and prefers to be in most of the day too. So now we have to make sure Moose and the cat are NEVER upstairs at the same time or there WILL be bloody murder. Abby is good and is fine with "Mu Shu" My daughter named her after the dragon on "Mulan" because she has white whiskers on a black face making her look like a dragon.
So, the animal rotation has been a real circus. But we love our animals.
Here is Abby (the small one) and Moose with my son. Don't have a picture of MuShu yet.
