I went ahead and purchased three NATURECALM collars for three of my cats. Two for pee issues and one for aggression issues. Nearly had a heart attack when one cat got it lodged in her mouth while it was still on her neck. I fixed that by making it snugger. I swear I notice a difference 12 hours later.

Do you all that use collars use this product or do you do something else?

TIA!
