^^ Really good thread!
Molly had different surgeries but I think the initial recovery needs (first 2 weeks until stitches/staples are removed) are pretty similar. We were never able to successfully crate train Molly so for confinement, we borrowed an X-pen rather than try to put her through the stress of crating. I doubled up some of the panels with zip ties so that the area was smaller and put the X-pen against our bed and a wall so she could be close to us. I also got an orthopedic foam mattress for her to sleep on in the X-pen.
I liked being able to keep a water dish in the X-pen because the post-op drug regimen made her a bit thirsty. I don't know if others have experienced this but Molly also cold not hold her pee as long as normal (even with factoring in the slight increase in water intake) so I put extra blankets on top of her bed that were easier to change out in case she leaked a little. I think the combo of tramadol and metacam for two weeks had some affect on her bladder control.
I kept her busy with frozen kongs (cottage cheese + green beans) and of course, reduced her food intake since she was sedentary.
She was able to use the cheap, fabric cone provided by the vet, but rather than keeping the cone up, I flipped it down so that she could still move comfortably, drink out of the water dish and the cone sort of draped over her body to deter her from licking the stitches whenever she curled up to sleep.
Good luck to you and Riley!!
