Sentry Behavior and Calming Collar for Cats, 1Ct, Purple

I’m reviewing again after a few years of not using this product. I have a very highly strung cat (the brown one). Lots of anxiety symptoms like PICA and aggressive tendencies to our other cat. It’s recently been bad (eating and digesting our mattress!), and he’s been full on aggressive with cat number 2 for about 6 months. I’d finally had enough and purchased this brand of collar (the original US version - and yes I struggled with purchasing an American product and supporting their economy at such political times, but it’s the best one! -I’ve tried the cheaper ones). Instantly our problem cat was calmer, cuddling and purring with us within 20 minutes, and no fighting with our other cat… in fact look at this photo 48 hours later! It’s worth the extortionate cost. It’s smells gently of sweets (candy), the smell is not over powering like the cheap lavender ones. The down fall is the collar ‘buckle’ - it’s terrible, if my cat was absolutely determined he would definitely be able to get it off by struggling with it. I’m thinking of making my own securement system. But for now he has behaved and kept it on.

First time bengal owner, desperately trying to find a way to calm down the maniac that is a 4month old kitten, he’s had these for 3 months and I have one in the cupboard still, he’s calm now so I haven’t needed to use it but I’m gunna put it in him for new years tomorrow since he’s terrified of fireworks and this will certainly calm him x 10/10

Didn't work for my cat unfortunately.
