Well, we've survived four nights, and each night it gets a little better. He still pitches a fit immediately, but once he calms down, he goes to sleep in the crate. Any further fits I think have to do with the bladder and not the attitude more than anything, but we still don't give in, so as to not create a bad habit. And he's already growing like a weed! I had to loosen up his collar already and it's just been four days!
Cats are doing ok - Chloe hasn't barfed in a couple days now (which I think is great) and Ty is playing with him in a mentor way. The puppy (right now) is limited to the living room, kitchen, and our bed and bath area. There are two other rooms that he doesn't go in that belong to the cats only, so I think they'll be all right.
He's such a cutie! I've already taken a complete roll of pictures and had them developed, since I have no website capability, you can email me at firstname.lastname@example.org
and I'll send a pic or two for you!
