“The sizing on these reads like they're tiny but I think treat the advertised neck size as being the smallest neck of the range the cone will fit? This size Small fits my larger cat who has an 8.5-inch neck, and perfectly. I use it turned in the downwards position. He's worked out how to eat and sleep with it on and is more comfortable than with the plastic one, but if the string's left a bit loose he's figured out he can pull it off. I noticed he can reach his back toes to lick them but that's not the area I'm protecting, so all good.”
