My old outdoor cat has an open nose scab. Can it heal on its own?

I would observe the lesion for oozing , infection , bleeding, excessive swelling, or even expanding. If none of this happens and it heals over the next week, then there is no need to take your kitty to the vet. Should the cut not heal, I would have your veterinarian examine it.

Poor Gizmo! I would definitely recommend having the scabbed-over area on his nose checked by a vet as soon as possible - cats sometimes get skin cancer such as squamous cell carcinoma that can present this way, and the nose is a relatively common place for this to happen. It's also possible that the area is infected, or that the scabs are allergy-related and will not heal unless this underlying problem is treated. Your vet can do some simple tests and may biopsy the area if there is any concern about cancer, and will advise you on what can be done to treat the problem depending on what is found.

It sounds like Mibaowa may have scratched at her nose, causing the scab to come off. It does need to heal, or it could get infected from her continually scratching at it. I would put an Ecollar on her, which will prevent her from scratching at it, and will allow it to heal. You can get an Ecollar from a pet store or your vet.

It is really difficult for us to help you with a question like this without a photo. My guess without having that is that the wound is healing fine and I would recommend you just leave it alone. Many wounds heal just fine without stitches. If you would like to post again with some photos we may be able to help you better. Best wishes.

She could have an infection, auto-immune disease, or allergic dermatitis. Since she has had the condition for about a week, she should be examined by your vet to determine the cause. She may need an antibiotic, anti-histamine, and/or an anti-inflammatory to treat the problem.

Hello. Depending on the size and depth of the wound, it will either just need time to heal on it's own (if it is not full thickness through the skin, and not too big. This will take a couple weeks. Just leaving the cone on, or getting a bigger size will help with this. Otherwise you can have the wound closed surgically. If you have a vet look at the wound they will tell you if surgical intervention is needed or not. Feel free to send pictures through a "consultation" and we can give you a better idea as well.

Poor Poppy! I don't see any signs of infection from the picture, but without seeing her in person, I can't say for certain. I'd have her checked out by a vet to be safe, especially since she is drinking less and staying more indoors.
