I suppose anything is possible,,but I can understand bear, they are not so wary of humans,,eat garbage or about anything. Mtn lions from the west,,yea I can see that, Colorado, Neb,Kansas,,alot of wide open country out there,,but wolves are a different animal. I also know of people that have dog/wolf crosses for pets. Saw one up near DesMoines. Attacked my dog in fact. Maybe escaped pets? Who knows? Just strange to me. I lived in N.Lower penn of MI. A decent wolf pop was established in the U.P. and once in awhile a stray wolf will come down across the Ice into the lower,,but way up there the sightings are rare. I am not worried about wolves or lions for that matter in SE Iowa. Tiny Ticks Yea,, THEY,, are the number one threat!
