Ohh sorry to hear about Paizley's incision getting infected. Did they prescribe Clavamox or Amoxicillin? Many vets can flavor the meds so they taste better, flavors like tuna, chicken etc. if it's a liquid anyways. If it's pills they can compound them and then flavor- they mash up the tabs and mix with a syrup with flavoring and you give with an eyedropper.

It's not uncommon for a spay incision to feel 'bumpy' or a little bit swelled since there are suture inside as well. Pus or any fluids coming out is infected and can usually be cleaned with peroxide, unless your vet has already prescribed an oinment or other treatment.

Hopefully she will be back to normal in no time.

Don't worry too much about Paizley. When Cami was spayed she kept licking her incision and got an infection too. A round of antibiotics and keeping the area clean and she was good as new.

As far as how to give the meds, I tend to use the same method kt_luvs_kitties does. I just get right down on the floor on my knees too. A treat afterwards and a good brushing or massage helps soothe the ruffled ego. lol
