I blame large chain pet stores too though. Here in the UK we have a chain called Pets At Home which is part of the American PetsMart chain. They recently started stocking degus. It drives me mad though, because they don't even sell degu food!
How can you stock an animal, but not stock the appropriate housing, food etc for it?
They've got their priorities all wrong. I have complained, but to no avail, I think something needs to be done on a larger scale.
I posed as a potential customer once and asked for more information, they refered me to an out-of-date book dating to the days that degus were first introduced to the UK as lab animals.
Cages etc - About these, that makes me so angry. I mean, I hate the size of my cage and it's 3ft tall! (just under 1m tall) As I said I want to build a big one, but that's besides the point.
Hamster cages?!?! I've seen pictures on the internet and on a few forums, people even congratulate some people on these cages, they are completely clueless. Just because an animal fits in a cage doesn't mean that it's necessarily big enough!
My other pet peeve is people who buy plastic cages / rodentrails for their small animals. THESE ARE DANGEROUS! Some people don't appreciate how much these tykes like to chew. Oh yes and pine/cedar bedding. But these things all make for other threads...
