Glad to hear that Lily is doing well after her surgery. It's normal that Toby hissed at her, as her normal scent isn't on her right now. All mine went through the same thing when they came back from the vets. It's like the others are saying,"Hey, you don't smell like my sis, who the H*** are you and what have you done to my sister." After a few hours and with her grooming herself, things will return back to normal.

Loved the pictures of your sweetie pies.
