Baby hedgehogs, known as hoglets, need extra help to survive the winter, and gardeners can make a real difference by leaving out food for them this autumn. British Hedgehogs, a charity, explains that hedgehogs can produce hoglets late in the season, and these young animals may struggle to build up enough fat reserves to survive hibernation.
The 450g Weight Threshold
The charity states: "The absolute minimum weight to see them through the winter is 450gms (1lb) and any hedgehog below this weight is likely to have problems when it hibernates." Autumn juveniles that appear healthy and are only active after dark will benefit from additional feeding in the garden throughout early autumn.
According to British Hedgehogs, hedgehogs should normally be rescued at weights less than 450g in late October to February, depending on weather and frequency at feeding stations. The charity advises seeking guidance from an independent hedgehog rehabilitation centre for the most appropriate advice at the time.
Feeding and First Aid Advice
Once in care, rehabilitators prefer to get autumn juveniles up to 600gms (1lb 6oz) or more before considering release, because they will lose weight initially upon re-introduction to the wild. For first aid, a hedgehog in need should be given extra warmth, either a warm hot water bottle wrapped in towelling or blanket, or placed on a heated pad with room to move away from the heat.
It should be placed in a box lined with torn newspaper, clean towelling, or fleece for bedding. If the hedgehog cannot be brought indoors immediately, outbuildings are acceptable if heated and flies cannot reach the animal, but the box should not be placed directly on a metal grid, wire floor, or concrete, as the cold will permeate through.
What to Offer and When to Seek Help
The charity advises offering meaty hedgehog food, meaty cat or dog food, or cat biscuits and fresh water, but never milk, as this can upset their stomachs. It notes that hedgehog casualties require specialised care, and the animals should be passed to an experienced rehabilitator as soon as possible.
British Hedgehogs recommends calling the British Hedgehog Preservation Society on 01584 890801 for details of the nearest independent rescue centre.
