Cats are rarer in the eagle diet, forming 3.4% of nest remains in the French Alps and 2.2% in the Republic of Macedonia. Mainly domestic cats (Felis catus) are taken but wildcats (Felis silvestris) are also known to be hunted. Rarely, the bobcat (Lynx rufus) have been reported as prey in North America and the remains from the much larger Eurasian lynx (Lynx lynx) (age undetermined) have been found in a nest in Sweden. A handful of accounts from North America and Scandinavia describe golden eagles hunting and flying off with small cubs of American black (Ursus americanus) and brown bears (Ursus arctos), of an estimated weight of . Similarly, the pups of spotted seals (Phoca largha) and harbor seals (Phoca vitulina) have reportedly been hunted. The golden eagle also rarely takes moderate sized dogs as prey. The only other family of mammals to be important in the golden eagle's diet is the hedgehogs, though these are only known as prey in Europe. The European hedgehog (Erinaceus europaeus) appears to be the most important prey species on the Swedish island of Gotland, making up 42.5% of sampled nest remains. In Estonia, the southern white-breasted hedgehog (Erinaceus concolor) was the most significant prey species (28.6%). The latter species was also the most important mammalian prey (13.8%) in the a small study in the Sarnena Sredna Gora Mountains of Bulgaria.
