Many animals will multiply and consume available resources without stopping. Cute bunnies left to their own devices on a lush meadow will multiply and keep eating grass until the is little grass left, upon which they will die en masse. Invasive fish crowd everything else out, insects that eat whole swaths of forest leaving no remaining habitat for themselves.

Perhaps animals who are territorial and fight, within-species, for territory can be considered to have a mechanism of self-regulating their consumption of resources.

Humans are perhaps the only animal that will even consciously contemplate the consequences of their actions on the environment. We are, I would say, the furthest from the virus.
