Why is my cat's shaved paw turning blue after abscess surgery?

Hello. Without a picture, I can not evaluate what you are seeing, but most likely you are correct & this is just bruising. Infection would take on a angry red color, so the light blue is nothing to be worried about. Thanks for using Petco Pet Education Center, formerly Petcoach.

I am quite concerned that the dark blue skin may be well on its way to a black color. Black colored skin is generally an indication that the skin has died. It is possible that some of the surrounding areas can die off as well, so I would make sure that the affected area is examined and trimmed away. An oral or injectable antibiotic would probably be very beneficial in this case to prevent further harm. Something else like an e-collar plus a steroid/antihistamine would help address some of the itchiness that Sunny is experiencing. If she continues to aggravate the lesion, the healing process can be slowed considerably or stopped entirely. Hope this helps.

Even though a picture would help to understand better the underlying cause, this presentation could be due to a trauma and/ or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and eventually antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid licking. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

It's hard to see what's happening in the photos, but if the ear is turning blue or black or is very cold to the touch I would be concerned that it isn't getting the right amount of blood supply to it for some reason. Other issues such as injury or bruising may also cause the color change, however it would be best to have it examined by a vet in person to look at it and treat as needed.

I am sorry to hear about Minibug. I would be concerned that she has a bacterial infection due to the wound. Puncture wounds can be very bad for this because it is extremely difficult to fully clean a deep puncture. I would also be concerned if you had wrapped her paw tightly with plastic wrap if some of the circulation to her foot could have been diminished. I would highly recommend getting her in to see a vet as soon as possible with the symptoms you describe. She likely needs oral or injectable antibiotics and pain medication.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on the picture, this could be an abrasion or a bruise from trauma. As long as there are no other bruises similar to this showing up anywhere else on the body, I would recommend keeping an eye on this for now. If it does not resolve or it worsens, then I would have this examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Yes the wound looks quite healthy and this is likely to be granulated tissue. Unfortunately this is a pressure point so the healing is definitively slower. Antibiotics are needed to prevent any infection.
