Hi Chloe the Human, I just now saw your other post about Chloe the Cat, poor girl! I am glad that the surgery went well.
With the same disclaimer that I am not a vet nor any kind of medical professional, it still looks ok to me for what I can see in the photos, although the pics are a little dark.
However, *IF* the cone doesn't stress her out too much, that might help put your mind at ease and certainly can't hurt her healing. When our civvie Molly was spayed as a kitten, she had a very rare reaction to the actual sutures, and it looked WAY angrier than this, she actually had to go back in to surgery after 3 days to have them redone. It was bright red at every point where the suture went in, bright pink and splotches on the skin all around the incision itself, and all of the bright pink skin actually felt hot to the touch. You could feel Chloe the Cat really carefully and see how it feels. But if you aren't getting discharge, it doesn't feel hot, the skin itself looks pretty normal and there isn't a lot of discharge or swelling, I think you are ok.
But I'd suggest running it by your vet in the morning, that is a perfectly reasonable after-care question for them. If you don't already have their email address, maybe just call their front desk and see if you can email/text the photos to the vet to look at, and then ask them to get back with you to see if they have any concerns and want you to bring her in?
Hopes for continued healing for Chloe the Cat, and for peace of mind for you
