Neutering: Post Surgery Scabbing *warning photos attached*

I'm concerned with whether or not I should bring in my 7 month cat to the vet because I can't tell if his incision is healing like it's supposed to. Him and his brother both got neutered at the same time and I thought it'd be okay to keep them together but they rough house too much so I separated them temporarily (he's staying with a friend). I also didn't have a cone on either of them. It's been almost two weeks since the surgery and I can't tell if his scab is a good scab. I don't see pus and it hasn't bled for a couple days now. I've read it can take 2 weeks or so of healing (knowing it takes humans a while to heal etc) He's eating normal and his stool is normal. He's playful and shows no indication of pain. Before I separated them I was using unscented wipes specially made for pets to clean the wound, but it hasn't been bleeding lately so I didn't want to mess up the scab or anything. I just get paranoid seeing people post worse case scenarios. I need a second opinion to see if anyone has gone through a longer healing process with their cat and if I should take him in. It's silly, but I don't want to spend $60+ just for a vet to say it's fine and there is nothing else I need to do but wait for him to heal.


This photo was a couple days ago.

And the others photos are from today.

The 3rd picture concerns me because it looks as if the incision has opened up. I'd get him to the vet just to be sure all is well.

Thank you for your feedback. The incision isn't bleeding so I don't think it has opened up (?). The fur around the scab is matted down. When I look at it up close I can still see the incision line.

Good!  You don't want any excessive inflammation or redness and definitely no oozing.
