Andrew took Slick out of his tank the other day.
It's been months since he's been out.
I grabbed the washcloth & picked it up - sometimes non-venomous snakes void nasty smelling stuff when you catch them - then headed out of the bathroom & met Stan, who was entering while pulling on some gloves.
After depositing the cute little fella into Miss Piggy's old digs (we have'ta keep it long enough for our 4-H campers to return & see it), we grabbed the National Audubon Society Field Guide to North American Reptiles & Amphibians and found him there in block 487 and/or 494 (details on p. 652) - a swamp snake!
My guess it that it was up by the house chowin' down on all the smaller-than-my-thumb-nail toads that scatter whenever I go to fetch the newspaper & mail. Stan said it was headed from the bedroom into the bathroom when he saw it so thinks it probably entered under the backdoor. No, we do not have a pet door.
