So far, so good! My cat is young and quite active! He loves to romp about outdoors! He has in the past, brought his catches indoors! Clearly very disturbing to me! I didn’t want to hurt his feelings, I know it’s his instincts. I needed to set him up to lovingly fail! It’s been almost a month, no catches! Not to mention he looks adorable! They are comfortable for him to wear all day, eating and napping is fine! I’m quite pleased!
