To protect small animals living in the city, Clinic 212 -- a creative marketing agency in Vilnius, Lithuania -- has created tiny road signs for these animals to “show that we are not the only ones living in the city,” the group wrote on its website.

The signs are intended to raise awareness and serve as a reminder to cyclists and walkers passing by that the Earth is a shared space between humans and animals, according to the Huffington Post.

Project manager Martynas Karpovicius installed tiny road signs in four different locations in the town of Vilnius, Lithuania, to protect birds, hedgehogs, ducks and homeless cats.

The idea came to Karpovicius while he was riding home in a cab at night.

“I saw a hedgehog passing through the street and it was so dark that the taxi driver barely saw hedgie,” he told the Huffington Post.
