One of the other volunteers that I know at the Rabbit Sanctuary, went through this with her rabbit a couple of years ago. Here is part of the article that her vet wrote, which we included in one of our newsletters:
Thus the story of Pez, the slightly underweight rabbit begins. Pez was rescued and adopted by a well-intentioned caretaker, who essentially became her “mom.” Pez was in good health and was fortunate to have a wonderful new home and family and her new mom was well educated in rabbit husbandry and management. Although mom was very concerned about her new rabbit’s trim physique of 6 lbs., her veterinarian was not. It is well documented that normal to slightly underweight people and animals have fewer health problems and a longer life expectancy than their over-weight counterparts.
In subsequent veterinary check-ups, Pez’s weight was recorded at 7.2#, then 8.0#, and finally reaching a full-figured 8.2#. Pez’s body weight had increased over 30% in a two and one half year period! Pez was so fat she had difficulty cleaning herself. Her skin was reddened and irritated from urine scald and her feces were clumpy. Her mom diligently cleaned Pez, applied medication to he skin and worked with her diet to correct the clumpy fecal material, but nothing seemed to work. During one of Pez’s daily baths, her mom noticed she had a belly pouch that inverted her skin, forming a pocket around her uro-genital region. The pocket was collecting her urine and feces, causing them to get caught in her skin folds. When the skin-fold filled, clumped fecal material just fell out into cow-patty-like piles.
Two problems needed to be addressed to treat Pez’s condition: she needed to lose weight and she needed a modified “tummy tuck.”
Pez’s skin had stretched out so much that weight loss would not alone correct the problem, so corrective surgery was scheduled. A large crescent-shaped flap of skin and underlying fat was excised to evert the pocket so it no longer could collect urine and feces. This amounted to a fairly radical tummy tuck according to standards in the human and animal world.
Fortunately for Pez, surgery was a complete success. Her mom was a wonderful nurse, giving Pez her post surgical pain medication, antibiotics, and keeping her incision line clean. Pez recovered completely from surgery. The fecal clumping and urine scalding were resolved. Now Pez is on a strict diet, being encouraged to exercise more, and is losing weight. Her mom has learned that even vegetarians need to watch their dietary caloric intake to maintain a waist line. Nibble like a bunny…yes just make sure it’s low calorie and it’s worked off.
