Mother cottontails only feed their babies twice a day, and a rarely seen. But, even if a baby cottontail is definitely orphaned, it does not necessarily need help. Once a bunny is the size of a softball, it no longer needs its mother’s care and shouldn’t be captured or “rescued.” Cottontail rabbits are extremely sensitive and often die from the stress of being captured, so it is important to leave them alone whenever possible. If you’re concerned about the safety of a juvenile bunny, keep your pets properly contained, and wait a day or two to mow your lawn.
