I think YT has saved Yoda's life several times now and made his life and Winky's better. They now have better nutrition, eat healthier food, have a good diet, and they have a bazilllllllllllllion toys through Gift Exchanges.
I think it's made me a way better parent for Yoda as I wasn't sure exactly how to be a Yorkie parent, as I've never had a real pet before, let alone a Yorkie... And of course, I'm a better parent to Winky as well, as I've learned an awful lot about Yorkies being here on YT for the last 5 years or so...
