A slower uncurl in the evening
A young hedgehog unrolls quickly, sniffs the air, and sets off on his rounds. The older version takes his time. He may stay balled longer when first disturbed, shuffle rather than scurry, run fewer wheel laps, and show a slimmer outline under the quills, with skin that looks looser over the shoulders. Appetite can become selective, favouring softer pieces, and he may be less inclined to anoint or explore new objects. Hedgehogs are solitary and stoic, so these gradual changes in a nightly routine are often the only announcement that age, teeth, or joints need attention.
Heat is not optional for a senior
African pygmy hedgehogs depend on a warm, steady environment, and an older, leaner animal loses body heat faster than a round adult. Keep his enclosure in its usual warm range with a reliable heat source and a thermometer you actually read, positioned away from windows and draughts, and check it during cold snaps and power cuts. A senior who becomes sluggish and cool to the touch needs gentle warming and vet advice, not a hot bath or a wait until morning. Add an extra fleece in his sleep house so he can burrow deep, and make sure the hide's entrance needs no climbing, because stiff legs and a high threshold are a poor match.
Wheels, floors, and feet
Keep his exercise wheel only while it helps him. It must have a solid running surface with no rungs or mesh that trap toes, and it should sit on the enclosure floor with a low step in. If he wobbles getting on, trips while running, or stops using it and seems relieved, retire the wheel and scatter-feed part of his dinner instead so movement stays gentle and purposeful. Check feet weekly for threads or hair wrapped around toes, long curving nails, and sore pads, since reduced activity lets nails overgrow and a less thorough groomer misses the early stages of a wrapped toe that can cut off circulation.
Teeth, weight, and the leftovers test
Read his bowl like a report. Whole pieces left while soft food vanishes, food dropped from one side of the mouth, a new smell on his breath, or drooling all point toward mouth discomfort that a vet should examine. Weigh him weekly on a small scale, ideally as he wakes, and keep a simple list of the numbers; a steady downward drift matters more than any single reading. Offer his established staple and insects in smaller, more manageable pieces rather than inventing a new senior diet, and make changes gradually.
Walking problems deserve prompt attention
Note how he walks every night. A slight stiffness after sleep that eases as he warms up is one thing; persistent unsteadiness, dragging legs, falling to one side, or inability to right himself is another and needs a vet promptly, because hedgehogs can decline quickly and several serious conditions begin with gait change. Blood in urine, straining, a lump under the jaw or on a leg, refusal of food for more than a night, or rapid breathing at rest all belong on the same prompt list. Handling on a fleece in your lap, close to the ground, lets you watch his gait across a soft surface and feel his weight in your hands at the same time.
Bringing a tidy history to the vet
Hedgehog appointments are short, and the vet cannot watch him all night the way you do. Arrive with the pattern written down: weights, when the wheel laps dropped, what foods get left, and how the walking has changed. KinsLe's Pet Passport holds that record in one portable packet, so an older hedgehog's carers and clinicians share the same facts instead of reconstructing them from memory at each visit.
