hey,

almost sure it's a young Black rat,I know by the coloring,its not a red rat,or yellow rat your to far north,same with Gray Rats,I can't think of any other Ratsnakes that may live in your area.

Rat Snake

they do okay in captivity ,if you acquire one young enough,and yours qualifies in that,we caught these in S.Illinois,full grown wild caught are a bit grumpy!!last show I went to some guy was selling 2 ft.ers but i went with another Yellow Rat instead,I tried to make him a package deal,but he wasn't ready for that yet,that may change at the next months show,because he also had a 4 ft. Gray Rat i was interested in,and with winter setting in,he'll need to move them fast,or spend more $ on feeding them himself,and the normal Ratsnakes aren't fast seller ether,everyone these days wants dam designer color's.another seller had a Florida Keys Ratsnake,Oh!I should have bought it!
