If you leave your gecko alone for two weeks with some lettuce baby food and a bottle top full of water will it be all right?

Leaving a gecko alone for two weeks with only lettuce baby food and a bottle cap of water is not advisable. Geckos require a varied diet that includes insects for protein and proper hydration; lettuce alone does not provide adequate nutrition. Additionally, a small amount of water may not suffice for their needs over an extended period. It's best to arrange for someone to care for your gecko or to make provisions for its needs before leaving.
