So I know this is a bird group, but I have some of the same problems. My 3 cats love to wander and chill with me outside... however the hawks have been getting very forward and are checking them out... not ok. My kitties listened to me yell to get in the house. My youngest (and biggest) was pressed against a fence. I yelled shook a can with nails in until I got him under a table and safe inside. The hawks continued to scout... we love to chill outside and I don't want to be afraid. I have been seeing, get a fake owl. Would it help if I put strands of lights all over? (Woot party house!!) with CDs around.. perhaps some windchimes for sound. Am I getting somewhere? Thanks so much!!!
