Wolves urinate on food caches after emptying them. [3]Caching behavior is typically a way to save excess edible food for later consumption—either soon to be eaten food, such as when a jaguar hangs partially eaten prey from a tree to be eaten within a few days, or long term, where the food is hidden and retrieved many months later.
Foxes cache excess food, burying it for later consumption, usually under leaves, snow, or soil.

[1] The Pinnipedia (seals, walruses and sea lions) are also assigned to this group. The center of diversification for the Caniformia is North America and northern Eurasia.
A predator's largest prey size is strongly influenced by its biomechanical limits. [34] Most canids have 42 teeth, with a dental formula of: 3.1.4.2 3.1.4.3. The bush dog has only one upper molar with two below, the dhole has two above and two below. and the bat-eared fox has three or four upper molars and four lower ones. [26]
