A rabbit's bottom is the end of him he cannot show you and the place where several serious problems announce themselves quietly: a soiled vent, blocked scent glands, sore skin, and in warm weather the fast-moving emergency of maggots in soiled fur. A short, calm examination built into the weekly routine catches the small version of each of these. Support and patience matter as much as sharp eyes: done roughly, the same check can injure a spine.
Prepare the Rabbit, the Surface and the Kit
Choose a low, stable surface he cannot fall far from: your lap with a towel across it, or a table covered with a towel for grip. Have a helper sit with you if he is a wriggler, one person supporting the rabbit while the other parts fur and looks. Lay out the items first: the towel, a small torch for pale fur or dim rooms, a dampened pad of plain water for testing whether a mark wipes away, your notebook and a food reward he likes.
Keep him upright, sitting, or rolled gently onto his side with his back and hindquarters supported along your arm or your helper's hands. Never tip a rabbit onto his back to hold him still; a rabbit lying tranced on his back is stressed, not relaxed, and a sudden kick against an unsupported spine can do real damage. If he struggles hard, stop and try again later.
Checking the Bottom Itself
Lift the tail gently and part the fur around the vent. What you want to see is clean, dry skin and fur. Note clinging droppings stuck to the fur, soft stool smeared around the vent, dampness that is there at every check, urine staining or scald on the skin inside the back legs, and any sore, red or broken patches.
A soiled bottom matters beyond tidiness: it can signal that he cannot reach to clean himself, that his diet is producing stools too soft to pass cleanly, or that his teeth or weight are interfering with grooming, all of which are findings to report rather than conclusions to draw at home. Wipe away only loose dirt with the damp pad; matted soiling and broken skin beneath it belong to the vet or nurse, who can clip safely and inspect the skin.
The Scent Glands
Find the scent glands as two narrow slits in the skin, one either side of the genitals, holding waxy secretion. Part the fur and open each slit gently with a fingertip; dark wax can build up into a hard crust inside the pocket, and the skin around it can look red, swollen or sore when the gland is blocked or infected.
Describe what you found in your note in plain terms: clear, light wax, heavy dark build-up, redness, swelling, or a smell stronger than his usual. Do not dig crust out with nails, pins or buds, because the skin of the pocket is thin and tears easily, and a torn, infected gland is a worse problem than a waxy one. Heavy build-up that returns quickly, swelling or soreness goes on the vet list, sooner if the area looks angry.
Urgent Findings and the Weekly Rhythm
One finding outranks all others: maggots, or clusters of small eggs in soiled fur around the bottom in warm weather, are a same-day emergency. A badly soiled rabbit who has gone quiet or off his food, and any wound under the fur, also go to a vet that day. Rabbits decline quickly once they stop eating, so a dirty bottom arriving with reduced appetite is two findings, not one.
In ordinary weeks, tie the examination to a fixed moment, such as the weekly full clean-out, keep it to a couple of minutes, and write one dated line: bottom clean or soiled, glands clear or waxy, skin sound or sore.
Recorded that way inside KinsLe, the Pet Passport history for a rabbit turns a keeper's hunch about gradual change into dated entries on cleanliness, glands and skin that a practice can judge in a minute.
