I know that we have the Rat Homes section for this, but it also includes questions about cages and "what cage should I get" questions. Could we maybe get a sticky thread of nothing but pictures? No conversations, just pictures of all the cages people have so other members can get more information and ideas about how to set up their cages? Then people could pm the person with questions about their cages, setup, and toys they've got in it.
Again, I know we can post pictures of setups in the Rat Homes forum, but they get lost really quickly as more people post. I've seen this on other rat forums as a stickied topic at the top of their Rat Home-type sections, and I think it'd be a good idea here too.
