Police said the tiger cub had strayed into a hamlet of Mountanchetti tribe, and entered the goat house and started attacking the goats, early today.
Hearing the bleats, the villagers rushed to the place and found the animal struck in the goat house, unable to come out.
They hit the cub with sticks and stones to save their goats, police said.
Forest department officials rescued the cub and took it to the hospital at the Mudumalai Tiger Reserve camp, where it is being treated.
