Wonderful!!
As all the other rat owners/previous rat owners, I will agree, they are great! I, myself, own 7. I couldn't live without them.
Good luck! And if you have questions, feel free to PM me.

And keep a VERY close eye on him for sneezing or any other sickness signs. Petco has a bad reputation for carrying sick rats (I know not all do, but I certainly know the ones around here do!). And just for a future referance, I'd say you'd need to find a vet that treats rats in your area. Rats will have to go to the vet atleast once in their lifetime usually, if not more. They're prone to such things as tumors, respiritory infections, and similar diseases. And treating a sick rat usually can't wait. Also, be aware most vets charge a pretty good ammount of money, as they consider rats to be exotics.. Just be sure to have plenty of money set aside for your new boy!
