Another nice WWF cover to add to my collection, thanks to Robert.
The stamps picture the European Wild Cat (Felis silvestris silvestris).
The Wild Cat is extinct in most parts of Europe and today it can only be found in a few parts of Scotland, Germany and Slovakia. Its natural habitat is thick forest land. This fierce, handsome animal is heavier and larger than the domestic cat and although rarely seen, can be distinguished by its thick bushy tail. Its staple diet is mice, voles, rabbits, hares and small birds at night. Mating occurs in March and most litters, of between one and eight kittens, are born in May.

These four stamps were actually printed in one sheet.
