They do indeed have shelters for hamsters and every other thing that creeps or crawls or flies.
Go to PetFinder.com and you will find every critter from frogs to goats up for adoption.
A *hamster* flashback for me ....when the kids were small we did the hamster/gerbil thing. Their favorite hamster, whom they named *Kissing Lady on a Bridge with a Moustache* had 22 babies. Thank goodness she ate most of them .... we couldn't find anyone who would take one in...b/c they already had their own hamster problem. This was in the days B4 the internet....even pet shops wouldn't take them for free.
Cedar shavings...expensive *Habitrails*...Oi! Not particularly pleasant memories.
