Hi - I'm new to this site and need help! I inherited a colony of around 17 ferals when I moved to my current residence. We have 4 acres and woods. My husband & I have gotten all of them spayed/neutered and my daughter adopted one. Number has decreased to about 12 now. We cleared out an 8x10 garden shed and put straw, boxes, toys, heat lamp and bought 6 bed mat/tunnels that are supposed to keep in warmth - but I can't get them to go inside! We are only feeding/watering in the shed now and they do eat but scatter if we are around. It was 6 degrees a few nights ago and only one cat went in and he was snug as a bug in the blanket tunnel. Any suggestions? Sorry so long. Thanks - Karen
