Glad to see Honey came thru the procedure well.
When Mandie was spayed, I didn't have a onsie so I used a tshirt on her. It worked because when she would bend to try to lick (which she really never did), the shirt would bend with her and go down..keeping the stitches covered.
What I had and needed was: Medicine syringe or dropper, pedialyte, mineral oil, nutrical, chicken broth. She wouldn't eat at first but when I drizzled chicken broth over her kibble, she ate (didn't wet the kibble..just drizzled enough really to get the "smell factor" lol). I used the syringe and pedialyte until the next day, then she drank on her own. I gave her some nutrical the first day because she wasn't eating much.
The mineral oil, I got because she got constipated (probably from the meds). I put a little bit (like an 1/8 tsp) on some of her kibble pieces and fed her. You can also rub a small amount on her booty.
