Yep, it's the second month we're using them and I'm not entirely sure if they've done anything. I've read that some cats respond better to other brands so that's another thing I'm considering trying once the current plug runs outhave you tried feliway plug ins ? they can reduce anxiety (doesn't work in all cats though)
I've more or less tried everything the internet has suggested. He has a water fountain (+ water mixed into his wet food which he does seem to prefer a lot more), several litter boxes in different places with various amounts of traffic around them, access to more cat furniture and high spots or hiding places. He gets access to outdoors occasionally but isn't overly keen and it's been very cold and wet anyway
I keep trying google and different forums to see what people have tried or done but I'm at a point where it's coming up with the same answers over and over again
