"1:30 p.m. Elephants are very strong—they can very easily crush and break most items with their trunks and feet. Therefore, any enrichment feeders and toys that we give them have to be “elephant-proof.” Securing the items in such a way that the elephants can interact with and not break them is a challenge that we face on a daily basis. Sometimes, it takes several keepers just to hang up one toy!" -Kayleigh Sullivan, animal keeper #WorldElephantDay
