Hugs
It's awful having to deal with this, and you always ask yourself if you're doing the right thing. But you're giving Cupcake the best life you possibly can. You're in tune with her and she'll tell you what's best. The important thing is to give her all the time she wants, enjoy every minute together and keep the good memories in your heart.
She is still the happy go lucky baby. She zooms around despite her back legs not working.
