Glad the stitch removal went well! I used the Purrkins onesie for a while even after stitches came out. (link below) Kitty may also leave the site alone now that the itchy stitches are gone! (Let's hope).

Great job on being and advoCAT (sorry I couldn't resist) regarding medications. I did the same with Yum Yum after her amputation a few months ago, and she did great after tapering off. Thankfully no recurrence of any phantom pain since.

Ok, so nice warm or even tepid damp facecloths over the incision a couple times a day should help the scab loosen and her itchiness. Get a facecloth or small hand towel and wet it well. Wring it tight and apply it like a compress.. don't rub. The skin is getting tight and itchy while healing, that's all. I had a very intense time with Huck when staples came out and I thought for sure he would do harm but he did not. Some do, some dont, just try to keep her comfy. That scab wont be on too long!

As far as the Gabapentin is concerned (again, I am not a vet) I would strongly discourage suddenly stopping it. I would taper off over a few days and do it gently. Huck was probably on for another week after suture removal and he did well being weaned off. They say less about cats, but with dogs they always wean. Just a thought. 

Sounds like a win win overall, yay for no sutures!!
