Wow, that TV is in your room? The TV I have in my living room isn't that big! *grin* I am glad your new little family now has a comfy, safe place - now, as nicely as I can ... leave them alone.
The 50/50 mix of the new food may be a little too much to start out with, I normally like to suggest switching over a 4 week period but since you've already done it, watch out for Momcat to have a little loose stool. It will pass on it's own, don't freak out about it, but it can happen.
Just so you know.
