I share your concern for your cat. If the paw is swollen, then the bandage is too tight and needs to be removed. It's ok to take it off. Do you have an e-collar for your cat? That way, he can't lick or chew at the surgery site. You can also remove and rebandage the leg more loosely. You probably have what is known as "vet wrap" on the outside of the paw -- it can be reused. Unwrap the leg, don't cut the bandage. Put the bandage back on loosely. The swelling will go down on its own after that.
I hope this is helpful. Please let me know if you need more information.
OK -- please don't worry. The stitches in the leg will hold things together just fine. The bandage is just an extra precaution. Your cat is on antibiotics so there is little increased risk of infection. You are risking a much more serious problem by leaving it on. The cat should be staying indoors and that will keep the wound clean enough. Please take off the bandage. It's the right thing to do. You can always re-wrap the bandage more loosely. If you don't remove it, your cat's circulation will be cut off and you will have more serious problems.
It will be fine -- trust me, I'm a doctor!
The white gauze should not be too tight, but to be sure, I would unwrap it too. You should remove the entire bandage. It's truly not a problem. Just be gentle when you remove anything that is "stuck" to the skin to avoid hurting your kitty.
Please let me know how it is going.
It sounds like you did a good job. Sometimes, when the outermost layer is stretchy like the bandage you had on, it can get too tight, causing the foot to swell. When not corrected, it can lead to decreased blood flow to the foot. You did JUST FINE! I'm glad all is ok today. GOOD JOB!!!!
I hope Gizmo is better soon.
