Some vets don’t send home much in the way of pain meds – my vet only sends a days worth home of metacam, to be given the day after surgery. We requested an extra dose for Stickers though, just in case. Different vets use different meds, but metacam is probably the most common (our vet charges $6 per dose). Ours was banana flavored too, but I had to hold Stickers against my chest sideways (with her side against me, so her tummy wouldn’t be touched/tugged on) while boyfriend syringed it into her mouth, she was not a fan of the taste.
Lintini, lucky. My male was so much worse than my female ! It took him over a week to be back to normal, the vet had me dropper water into his mouth to keep him hydrated because he refused to drink he was feeling so bad after the neuter.
Stickers was back to normal after 3 days, I had to watch her because if she got freedom she wanted to run around doing high jump binkies and I didn’t want her to break her incision open.
If your vet is good, flopsy should be FINE. Just make sure she’s comfy and has easy access to food and water, since they don’t like to move around too much right after. And clean, clean, clean. Don’t be surprised if she lays in her litter box when she gets home, so make sure that is scrubbed with vinegar before she gets home.
