Personally I have a very complex avatar it seems why the normal sized kitty is huge for me especially if I hold it cuddle works better.
A 5 days old kitty would work perfect to cuddle and hold for my avie

I noticed also avatars in SL become smaller over the years I had a conversation about this trend yesterday with Deerylou as well.
First I was considered by many as too small and currently I'm pretty much a normal size compaired to others yay!

Thank you for your suggestion because I'm all for more sizes and variations in this when it comes to our pixel cuties!
I think also more variety in sizes would be cool for the market as the Toys and Teacups come random and they are so valued by many.
