Obviously wish #1 is a good home. If you’ve already got as many little furry children as you can handle or can’t adopt for some other reason, well, you can still help the four-legged needy.
Fairfax animal shelter put out a cutely-worded announcement that they have a holiday gift wishlist of their own, but the fact is that all our local societies have needs – yuletime or not – and many will take in-kind donations. The Washington Human Society also will take in-kind donations if you’d like to give rawhide chews rather than money – though they’ll take cash too. The Arlington Animal Welfare League will also take your donations of money or stuff[pdf].
The Montgomery Country shelter only explicitly mentions monetary donations; same for the Prince George’s County shelter. But if you really want to give stuff rather than cash, give them a call – it’s possible they’d be happy to have it.
