|Yeti loves cats.|
There's a brand new preschool kids show on Amazon Prime - just a pilot - but response is very positive so a full series seems possible - that is about a cat who is friends with a yeti!
It's stop-motion animated (yay, stop-motion!) and it's called: The Curious Kitty & Friends
An example of the Relucant Monster trope.
Although I can't find official confirmation, it seems pretty clear that The Curious Kitty & Friends is an American adaptation of a Japanese kids show - Little Nekko 꼬마네꼬 - which also had the same yeti friend for the purrtagonist. But he looks a lot less polished and friendly than the American version.
