Well a cage for a hamster is different than a crate for a dog for one thing. But it doesn't really matter which animals require more work. The fact is no matter the animal they should be getting the care the require. Because they are cheap, or small or can live in a cage/tank/etc. people assume less of them. My dwarf hamster doesn't require that much work. I do partial cage cleanings on her cage every week or two, full ones every 4 or so months, she gets food daily, I prepare fresh food too for her, I check her over every few days for any health issues that might have shown up, and I make sure she always has something to do. I would handle her if she wanted it, but as a roborovski she fits right in with the characteristic of being shy. The only reason she doesn't get a lot of out of the cage time is because she is happy in her home: Just because she's 2" long and cost me $5 doesn't mean that she does not deserve the care she requires. Most people don't care enough to do the research though and others of her species suffer because of it. The same happens of dogs, of fish, of reptiles, of cats, of any animal. Sad but true.
