Glucosamine is a key factor in stimulating bone cells to produce more collagen, proteoglycans, and chondroitin sulfate. This is the process the body uses to rebuild cartilage. If cartilage metabolism is supported, the reversing of cartilage damage and joint pain often occur.
These Kool Kat collars are perfect for my hyper 2 1/2 yr old cat, Julio! He can get out of a breakaway collar in seconds. These collars, though, stay on! He did wiggle out of the collar once when it got stuck and almost wriggled out the other day when I was holding the collar trying to restrain him. Since the collars are stretchy enough to allow him to get out of them in emergencies, I feel quite certain that Julio won't strangle himself on the collar. Since the Kool Kat collars don't have breakaway buckles, though, he keeps the collars ON except in emergencies.
The colors are true to the pictures in my experience and are colorfast. The 12" collar is about 1" too long for him but that inch was easily cut off and the end sealed with brief application of a lit match (NOT while on the cat!). The Kool Kat collars are soft and flexible so they don't irritate Julio's skin or rub him in places. Julio seems very comfortable in his collar except when the collar fraying becomes extensive - which is easily remedied by taking the collar off him and using embroidery scissors to trim the frays every few months.
I'm so glad that KV Supply carries these collars - they're impossible to find locally. And the breakaway collars just don't stay on more than a minute or two at best. These Kool Kat collars have been a perfect answer for Julio!
