Hearing that your rabbit, guinea pig, ferret or rat needs surgery can be scary. Many families have heard that anesthesia is risky for small animals, and it's natural to worry. The good news is that careful monitoring, species-specific anesthetic plans and thorough pain control have made surgery much safer than it used to be, and good preparation at home helps too.
Exotic companion mammals have a fast metabolism, lose body heat quickly and hide pain very well. Rabbits and guinea pigs also depend on eating almost constantly to keep the gut moving. Pain and stress slow the gut, appetite and healing, so I plan every anesthetic around four goals: keeping your pet warm from start to finish, monitoring heart rate, breathing, blood pressure and oxygen levels closely, controlling pain before, during and after surgery, and getting your pet eating again as soon as possible.
Good pain control combines medications that work in different ways, so each can be used at a lower dose with fewer side effects. This is called multimodal pain control. Depending on the patient and the procedure, a plan may include local "numbing" blocks like the ones a dentist uses, medication given as a slow, steady drip through the IV line during surgery to reduce the amount of anesthetic gas needed, opioid pain medication chosen for your pet's species (each species handles these drugs differently), and anti-inflammatory medication, which I usually start after surgery once your pet's temperature and blood pressure are stable.
I'll examine your pet first and may recommend bloodwork, and for older pets, X-rays or other tests.
Food and water instructions are where exotic pets differ most from dogs and cats. Rabbits and guinea pigs usually should not be fasted, because they can't vomit and their gut needs a steady supply of food. Ferrets and some other species may get specific instructions. Always follow the instructions for your individual pet rather than general advice online.
Pack a small bag of your pet's usual hay, pellets and fresh greens, plus a familiar towel or hide.
At drop-off, tell the team about any medications or supplements your pet takes, and any changes in appetite or droppings over the last day or two.
During the procedure your pet is monitored continuously. Priest Lake Veterinary Hospital uses IV fluids and monitoring such as EKG, blood pressure and pulse oximetry, with pain management during and after surgery. Prey species are housed away from dogs and cats, and I aim for a warm, quiet recovery space.
The procedures I perform most often include spays and neuters (depending on species and size), mass removal such as mammary tumors in rats, dental extractions, abscess surgery, bladder stone removal, abdominal surgery for problems like intestinal obstruction or liver lobe torsion in rabbits, ferret adrenal surgery, and rabbit nasal and ear surgery.
Set up a calm, draft-free spot with a hide, and place food and water near its entrance. Offer fresh hay, greens and the usual diet right away. If appetite is slow, I may send home a recovery food to syringe-feed.
Watch the droppings closely. Normal-sized droppings are one of the best signs of recovery in rabbits and guinea pigs. Give pain medication exactly as directed, and don't stop early just because your pet seems fine, because these species hide pain. For rats, use paper towels or fleece instead of loose bedding, since some pain medications can make rats chew and swallow non-food items. Check the incision daily for redness, swelling or discharge, and prevent chewing at it.
The real sign of a good recovery is the return of normal behavior: eating on their own, grooming, exploring and stretching out to rest.
Call right away if, after surgery, your pet hasn't started eating when expected, is producing few or no droppings, is breathing hard, is weak or cold to the touch, or has bleeding at the incision or has opened it.
Call the same day if your pet seems painful or hunched, is grinding their teeth, or the incision looks red, swollen or has discharge.
