I tried to respond to this earlier but clicked the wrong thing and it went *poof.* Anyway....
I can't find detailed writer's guidelines for CRITTERS USA but in the front of the magazine I found this bit:
"Unsolicited manuscripts and photographs are welcome on an exclusive basis, but none can be acknowledged or returned unless accompanied by a stamped, self-addressed envelope."
Here's the address:
CRITTERS USA
P.O. Box 6050
Mission Viejo, CA 92690-6050
The editor's name is Melissa L. Kaufman.
CRITTERS is published by the same company that also does
Ferrets Magazine (and a whole buncho other pet pubs). That link takes you to the guidelines for Ferrets Mag--I'd guess they'd be similiar? But because CRITTERS is an annual publication, you'd probably better get your query in now for next year. Woohoo!
Go get'em, Rattitude.
