i feel slightly silly posting about this, of all things, after a year of absence but hey. Fancy Rats | Home is a good place for information. definitely get at least a pair of rats! P.A.W.S.S Pet & Animal Welfare Support Service Aberdeen often has rescues needing homes. there are a couple of reputable rat breeders towards dundee and glasgow; if you buy from them, you're buying a rat that is almost guaranteed to be much healthier and longer lived. does bought from pet shops are notorious for developing mammary tumours and both sexes are more likely to struggle with respiratory problems. i can't offer much advice on the cage - i'm a diy dunce - but make sure you make it big enough. while they're young and mobile, you'll be able to get away with a tall cage (as opposed to a low one that takes up loads of floor space) if you put in shelves and hammocks so there're no long drops. sawdust is really, really bad for wee furry animals so avoid that. carefresh is a good but relatively expensive alternative. bedxcel or ecopetbed are huge bales of chopped up cardboard (marketed as horse bedding) which are cheap as chips and do the job perfectly if you can get your hands on them. biocatolet or bob martin's 100% paper cat litter are other options. you can litter train rats so you have to do a full cage clean less often. the rat nuggets pets at home sell are pretty good but the best diet you can give them is home made. it's a bit of a pain to make but if you do a lot at once, it keeps in a plastic box for ages. if you get bucks, don't let them eat orange peel or mango. does are okay with them. rats can't burp or vomit so don't let them drink any fizzy things and obviously alcohol's not good. i can't remember exactly why but caffeine is bad too. mine usually go bananas for a little chopped up boiled egg or bits of spaghetti. i don't bother buying many expensive toys any more - my rats get old cardboard things (they love tissue and egg boxes) to play with and destroy. a hammock can be as little as an old trouser leg safety pinned to the side of the cage. if you really want to buy toys, a lot of parrot things are well suited, as are the ropes with endy bits that screw on the the side of the cage. they need a lot of "free range" time too - so if you can tidy up any loose wires, close the windows and doors and make sure there're no holes in your skirting, they'll run around and explore quite happily. keep an eye on them though - i've had a few that just can't resist crawling down the back of a sofa and chewing it up from the inside. i should probably stop there.
