Kasha gets spayed too Friday! I'll think good thoughts for both our babies!
I have to get her a onsie too. What size did you get? My Scottish Terrier was spayed when she was 6, she had NEVER worn clothing in her life, but she was pretty out of it so she tolerated it & I'm sure that the cone would have been worse. I'm sure Mya will be the same. :-)
Goodluck!
