Just parts of animals have been used to make glue. Animal collagen has been used for thousands of years to make glue. Hides from mammals, fish have been commonly used. Horses (often said to be "sent to the glue factory), cattle and pigs have been used. These days, most glues are synthetic.
Animal hooves and sinew were used a lot. Now they are used in very limited amounts for specialist wood glue for restoration.
About 200-300 years ago many animals with hooves and tendons were used to render down to make glue. Fish bones were also used until quite recently. I remember being taught to use it in school woodwork class. -Now a small amount of animal glue is still made by specialist companies, mainly for antique restoration.
Hoofs and tendons used to be boiled down for glue. -Now most modern glues do not use any animal parts.

An animal glue is an adhesive that is created by prolonged boiling of animal connective tissue. These protein colloid glues are formed through hydrolysis of the collagen from skins, bones, tendons, and other tissues, similar to gelatin. The word "collagen" itself derives from Greek kolla, glue. These proteins form a molecular bond with the glued object. Stereotypically, the animal in question is a horse, and horses that are euthanized are often said to have been sent to the "glue factory." In fact, animal glue is produced from a variety of different animal species besides horses.
