Ace,
I'm really SUPER GLAD you found a new friend.
Don't worry about the sleeping, the little fella has been overstressed for how long?
when we had Ralphy, ( our Big white cat) come live with us we thought he had narcolepsy. He would walk 3 feet then just fall over and flop on his side, sound asleep for 2 or 3 hours.
He eventually got over it and is now a normal, BIG 15 pound kitty boy that is spoiled rotten.
I think what happened was that he had had such a rough life before he adopted us, (broken hip from a kick, broken nose from who knows what), terrorized by dogs, (he will not tolerate a dog and killed a 30 or 40 Lb German shepard the day we got him). Lived in a shelter a few times when he wasn't responsive to the new owners, (He's deaf as a post-- I've fired my 10MM right beside him and he doesn't budge).
It took about 2 or 3 months of love and spoiling to bring him around. Now, he sleeps wrapped around my wifes head and has to get up with me at 2 or 3AM to make sure I'm OK. I know many times that I'm gonna have a medical problem because he won't let me alone. He meows, whines and snuggles tight. Actually, he doesn't meow, ... he never learned... He says, Ralllllpppphhhhhh! Hence the name.
All in all, he will become part of you, heart of your heart, and a trusted friend. He will make a place in your heart and you will make a place in his.
He isn't taking the place of the old pup, he's making a new place for himself.
Now it's up to you to make a place for him.
Sorry to wax female, or sensetive, but our pets are aneeded part of our lives and if it wasn't for people like you, he wouldn't even be a memory now. He'd be smouldering along with a pile of other unwanted animals.
