CONGRATULATIONS!
I had my surgery on April 9th 2018 and am almost 2 months post op.
I'm not doing to lie the first month was grueling!! But now that's past its smooth sailing from there!
Just make sure to keep extremely good care of your kitten and follow everything they advise you do.
P.S you have to keep it as dry as possible until its healed, i recommend getting thigh high socks so you can have her exposed without getting cold. Also strong toilet paper so it doesn't leave any flakes on her after peeing. (sounds silly but its true!)
Good luck!!
