Yes, I have to say the yowling and such is a twist! Mine run away and try to hide, but the tiny girl is quick and catches them a percentage of the time. I didn't have luck with Clomicalm or the calming collar or various calming treats. I do have the multi-cat version of Feliway in the room they stay in the most. I'm not sure it helps but the refills are reasonable enough at Chewy that I'm still using it. You could consider a trial of CBD oil for both of them perhaps. It has been the thing that has worked the best for my kitties, but everyone's mileage may vary. It is supposed to be good for both anxiety and aggression, and that bears out so far here. I get the pet version at Lazarus Naturals because it is lab analyzed quality and reasonably priced. They only need 5 drops twice a day (on their food) so the larger bottle lasts a pretty long time.Okay, that's what's weird, because Coffee has no desire to be alpha either! I wish Maui would just leave her alone. It's like she thinks that Coffee is her own personal toy, and I think that because Coffee reacts SO animatedly, Maui keeps doing it and hasn't gotten bored of this behaviour yet.
