I feel less guilty when Weasley slips out of the house. I.try to make my yard bird-friendly with a commitment to native plants for them. I'd hate if I were just luring the birds to their death. The collar no longer seems to bother Weasley, yet it seems he is less inclined to slip out. (My daughter says he's embarrarsed to be seen lol).
I haven’t let the cat out yet so am waiting to see how it actually works to save the birds
I just got it and put it on the cat. It fits well. I thought it would wider but it seems ok. I like the reflective edging. I only got for one cat and the other cat started to attack the one with the collar. I’ll report back when I find out how effective it is for the bird situation.
Birdie (my former roommates cat) got a fresh new collar recently
My former roommate's cat started bringing me birds and she now happily accepts her Birdsbesafe collar and has never caught a bird since so I know your collars really work and plus she looks extra adorable.
