Post-surgical monitoring and care
1. Warmth
Immediately after surgery, keep your bunny warm and quiet.
Provide a warm water bottle or other heat source (that can’t leak, burn, or cause injury) wrapped in a soft towel for bunny to lean against or move away from, at his/her discretion. DO NOT use any type of electrical heating source that could be an electrocution risk, should bunny chew on it!
Rabbits will tolerate a soft, light blanket better than a heavy one.
**In my experience, i used to put uncooked rice inside a sock and microwave it. I think beans also work.
2. Post-surgical Contact and Handling
Don’t hover. A bunny after surgery may feel groggy and unhappy, and not in the mood for cuddling.
Unless you know that your rabbit wants cuddling, it’s best to let him/her recover quietly and without more human interruption than is necessary to ensure that all is well.
3. Post-surgical Monitoring for Trouble
Be sure to carefully (and gently) check the sutures daily for a few days after surgery to be sure the bunny isn’t chewing them.
Many vets use subcuticular (under the skin) sutures that cannot be chewed out, and may even put a line of surgical glue over the incision for extra strength. Ask your vet about this before surgery, so you will know what to expect.
Be alert for excessive bleeding (a bit of oozing is not unusual, but outright bleeding is a cause for concern)
Excessive redness or signs of infection such as swelling or pus are not normal.
If you see anything that causes concern, call the vet immediately for further instructions.
If your rabbit hasn’t eaten anything within 24 hours of surgery, contact your veterinarian.
