Australian viewer here who is only now getting to watch this latest season, so forgive my rather untimely remarks. I've watched two eps so far.
Re the first episode I saw with Zeus the savannah cat and Sebastian, I really enjoyed the Zeus part of the episode because there's something about a decent and devoted "cat daddy" which really resonates with me. Beautiful cat but perfectly easy to understand how a cat of his background would be literally climbing the walls in a small apartment without lots of other stimulation. I totally agree with the above poster re Sebastian and his owners. Talk about unprepared! I find it hard to relate to episodes with truly problematic cats because in all my years as a cat owner (or being owned by cats, more like!), I have never had any that have behaved like that. My current kitty, Claude, is 15 years old and has always had the most beautiful nature. He would no sooner bite or scratch me than fly to the moon. And the only time he has ever hurt me is accidentally, when I am trying to get into his cat carrier, because he hates it so much and will go into a "bat" position and strike out to avoid going in. But that's it. I don't know how Sebastian's owners put up with his aggression for so long, unless they really didn't think there WAS a solution?
Awww, I thought he was wonderful, and what a beautiful, sweet kitty Elsa was. As someone said upthread, it's nice to see episodes about cats who aren't just out and out aggressive, but have other types of behavioural issues. I also got quite misty-eyed over the blind cats and their foster carers, especially while watching the ginger one playing so happily. The Meki half of the episode, I found myself getting rather frustrated with his owner because she just couldn't see the forest for the trees and that she was a huge part of the problem. I've never seen a cat who would willingly want to go under their owner's shirt for comfort. He's a cat, not a kangaroo joey who needs to be in a pouch to feel safe!
