SENTRY Calming Collar for Cats and Kittens, One 30-Day Release Collar

if it works on an "anxious" cat, it's never indulgent. that cat was so ...angry and bratty. I'd watch him run so fast across the room... fast. turn around, size up the run back across and tear up anything in his path. new adoptee. he seemed layed back at pound. he was not. he was furious. I think he loved his original female owner and...the guy did not like him. he also had his eye damaged.. seemed as tho it might be from some one trying to spray him to correct him. I needed calm down stuff. this worked very well like night and day. I kind of felt bad. took it off the next day (doing what the instructions said not to do). put it back on. we are coasting. he's calming down and accepting me more. he tried to size up the room a couple of times, but I can talk him down. not perfect, but definitely adjusting so much better. cute even. his new sister has other views. this collar works. don't take it off once you put it on. he didn't seem to act or feel too medicined up. just way more pleasant. the collar extra part can be left on and be more medicine. I didn't realize that and cut off the extra. we're fine. I think they also sell 3 in a pkg and it's a better buy. but don't cheat yourself. not all collars are the same and the cat treat calming didn't work for me. best of luck. my sister cut off the excess collar and used that for a collar the next month. after about 4 months she didn't need collars as much for her cat. my female cat, I tried the collar on her. no. she was mean bc of lack of trust. not hyper. just very bitter. it's a year now. she's leaning to trust. best of luck.

These have helped my cats so much. She was peeing all around the house and we couldn't figure out why. These have calmed her down and made her much nicer cat plus the peeing has stopped.
