What a healthy incision looks like
A healthy spay incision is generally a clean, straight line on the lower belly, with the skin edges touching. In the first days it may look slightly pink or red, and the skin right along the line can be a little puffy or form a small firm ridge. Some cats have mild bruising. The area may be shaved, and your vet may have used stitches, skin glue, or staples. Closure methods vary, so ask your clinic what was used.
Healing timeline, stage by stage
These are general ranges, not guarantees:
- First 24 to 48 hours: mild redness and swelling are common, and a small amount of clear or slightly pink fluid can be seen early on. Your cat is usually sleepy.
- Days 3 to 7: redness should settle down, and thin scabs may form. Energy returns, which makes it tempting to let her jump.
- Days 8 to 14: the skin surface usually finishes healing. Any external stitches or staples are generally removed around this time, if your vet used them.
- After two weeks: deeper tissue continues to heal for several weeks, which is one reason some vets still advise limiting hard activity.
Normal vs. concerning signs
Usually normal:
- Edges together in a neat line
- Light pink skin and mild swelling that improves over days
- A thin scab or a small firm ridge along the line
- A slight amount of dried clear fluid early on
Reasons to call your vet:
- Gaps or edges pulling apart, or tissue showing
- Pus, thick or discolored discharge, or a foul smell
- Active bleeding, or discharge that continues past the first day or so
- Redness that spreads, hot or hard swelling
- A cat that is very tired, refusing food, or vomiting repeatedly
If you find a bump along or under the incision, see lump under a cat’s spay incision.
Is it normal for the incision to look open?
A properly healing incision should look closed. If the edges are visibly separated, if the incision looks wet and gaping, or if you can see anything beneath the skin, contact your vet the same day. Tiny gaps near a suture can occur, but only a vet can judge whether it is safe to monitor. Do not try to push anything back or close the wound yourself.
How painful is a spay?
Spay surgery is major abdominal surgery, and cats do feel some discomfort afterward, although they often hide it. Vets typically provide pain relief during and after surgery. Signs of pain include hiding, hunching, crying, reluctance to move, or not eating; our guide to the signs a cat is in pain lists more. If you see these signs despite medication, call your clinic. Never give human pain relievers such as ibuprofen or acetaminophen, which can be toxic to cats.
Caring for the incision
- Check it once or twice a day, at the same times if possible
- Prevent licking with a cone or recovery suit
- Keep it dry and do not bathe her unless your vet says so
- Do not apply creams, alcohol or peroxide unless prescribed
- Limit running and jumping until your vet clears her

Cone timing: can it come off after 5 days?
It is common for a cat to look recovered by day five, but the incision is usually still healing. Many vets recommend leaving the cone or suit on until the recheck or around the 10 to 14 day mark. Ask your clinic before removing it, particularly if you see any redness or scabbing.
What to do if stitches open
If an incision opens or you see stitches coming apart, call your vet promptly. Keep your cat from licking the area, keep her quiet, and follow the clinic’s instructions on whether she should be seen right away. If tissue is protruding, treat it as an emergency.
