When I purchased this collar, my male cat was bringing a minimum of a bird a day into the house (mostly finches). He has worn the collar for 3 weeks now and has brought a hummingbird in the house (which I was able to rescue and put back outside.).
I have found zero dead hummingbirds since our cat started wearing this collar. He tolerates the collar well and I highly recommend it!
My nine-year old cat is an avid hunter. She was bringing in a kill, or live bird almost every day. I originally purchased the giant bell for her collar from this company and it worked for four days. This collar has worked now for three weeks. No birds, lizards, or rats (dead or alive) in my house for THREE WEEKS!!! Whereas I used to tentatively walk into my kitchen every morning, steeling myself for some level of carnage requiring a cleanup crew, I can now start my mornings on a joyful note. I highly recommend this product. If you have a bell on your cat's collar that you want to keep, I recommend putting a small stitch on each end of the openings to keep the bell from sliding into the fabric tube. The tube is rather wide and presents some issues, but they're not insurmountable - and applying a couple of small stitches helps a lot.
Sasha had killed five birds within 10 days (two on one day), then I put him one of the collars from the three-pack, and he has only able to catch one bird in the last month (as far as I know - I am pretty sure he takes all of his catches into the house). Kudos!
I've been using birdsbesafe collars for two years now. My cat used to catch and bring birds inside my house often (one time 5 birds in a week, yikes). In the past two years I have seen him catch maybe 3 birds, so the collars seem to help considerably.
I give him a treat when I put the collar on or take it off and he really doesn't seem to mind it at all. He has lost two collars, dunno know where or how but I guess that's good proof that the breakaway works!
Also really appreciate the reflective trim and I love how the ruffs make him look like a goofy little clown <3
Certainly cut down on the bird deaths but not entirely. The “clown collar” is well made; be certain to have your own internal collar. Definitely take it off when kitty is indoors, tends to bother his neck-perhaps all of the folds of the collar?
So far, this seems to be working. I have a cat that loves to sit out on the patio with me, but I needed to tame her killer instinct with birds. It is costly, at $55. Now that I have it, I see that it is simply an ordinary safety collar with a little bell, along with three different brightly colored fabric "tubes," which I think would be very easy to sew at home out of brightly colored fabric. Each one is simply a 12" by 2.5" tube of fabric, open on both ends, that the collar slips into. The collar then fastens at the open ends of the tubes and the bell hangs down at the opening. There may be something about the particular colors and patterns that is effective here. In any event, I notice when I sit out on the patio, I don't hear chirping like I used to, so maybe the birds leave as soon as they see my cat in this. Either that or she's already killed all of them.
