Comments about Sergeant's SentryHC Good Behavior Adjustable Calming Pheromone Cat Collar:
Highly allergenic to some people--hay fever sxs--sneezing started immediately--probably the lavender (my guess)--had to get it out of the house. Dog seemed to like the smell & was attracted to it. Might be worth a try if you and your friends and family don't have allergies.
Comments about Sergeant's SentryHC Good Behavior Adjustable Calming Pheromone Cat Collar:
This has worked better than medication for an aggressive (to other cats) neutered male cat.
Comments about Sergeant's SentryHC Good Behavior Adjustable Calming Pheromone Cat Collar:
Greatly helped my three year old neutered male cat not be so aggressive to two older cats. He was more loving, too, but I think I will replace before one month as effects are starting to wear off after two weeks.
