Grey Seal Pup Feeding

Grey Seals are one out of two seal subspecies, which are native to the UK. This seal subspecies is born in a white non-waterproof fur coat, and will moult into the first adult fur coat after mum leaves them (when they will be 17-23 days of age).
While the grey seal pups are still with their mum, the pups do feed often as they do need to drink about 2.5 litres of the 60% fat containing milk per day (to have enough reserves when mum will leave them.
