I've gotten 3 males, they're the kind with the elongated heads and small ears.
I'm open to pretty much any advice, but in particular, I'm looking for:
Cage layout advice (How do you have your cage set up? Photos would be terrific.)
Suitable bedding material. (The woman in the pet shop said cat litter is good?)
General hygiene and odour control advice.
Training advice. (I've heard rats can learn tricks?!)
Diet advice. (I've bought some Pets At Home branded nuggets, are these good?)
Suitable toys and treats advice.
