Carol,

Welcome to Pet Talk! Congratulations on your adorable granddaughter Misha! So glad your sweet Oscar is home -- I know Randi's Fister, Phred's Boots, and KAK's Cirrus have had the surgery within the past 6 months to 2 years -- perhaps they can chime in here with more info.

Warm regards,
AmberLee (Meowmy to Cassy and Livvy)
