I second everything Doodles said!
For Esther’s spay 4 months back, I set up her recovery area right next to my bed so I could monitor her at all times. My apartment is laid out oddly, and it was the best option. She’s free range and has always been energetic, so I knew I would need to keep a constant eye on her to ensure she didn’t escape. I filled her area with blankets and toys she’d already chinned and laid around in to help make her more comfortable, and I really think it helped. I also set up a corner with a little half-curtain so she could have some alone time and didn’t feel too crowded by my constant presence. For the most part, though, she wanted constant pets, ear rubs, and affection. My vet suggested about 3 feet and a recovery period of at least 10 days, so it seems like there’s some variation- definitely confirm with yours what is right for Luna.
If you have an escape artist, consider rigging a lid/ceiling for the top of the recovery pen. Esther broke out Day 2 because I didn’t think she could make a 2.5′ vertical leap, and she proved me wrong. Luckily there was no tearing, but it was an eye-opener. I used some NIC grids as a ceiling, and they held out great.
I highly recommend using white paper litter instead of anything with color or just hay. If the stitches tear, you’ll be able to see drops on the white litter right away. I bought a litter box for an elderly or baby bun with a very low entry point so Esther wouldn’t run the risk of rubbing her tummy on the edge, and wouldn’t have to work too hard to get in. I started the recovery litter box off with some of her used litter so she understood this was her new bathroom spot. Worked out great.
Her body temp was really low the first three days, so during her long naps I would tuck a very thin, very soft fleece pet blanket under her ears and along her back to help her retain more heat.
For her medicine, the vet walked me through the burrito but I definitely didn’t get it right the first day and was scratched to pieces, so I tried just letting her lick it off the dispenser a drop at a time. That stuff must be delicious, because she went crazy for it!
For food, I started with hand feeding every hour as soon as we got home to encourage her, peppering in tiny bites of banana into a mix of her favorite greens & hays. She wasn’t eating anything but what I was hand feeding her on Day 1, and then started eating on her own on Day 2.
Best of luck to you & Luna! I’m sure she’ll do great!
