Does no trespassing signs apply to animals as well?

No trespassing signs are primarily meant to deter human beings from entering a particular property without the owner's permission. While the signs may not specifically mention animals, trespassing laws generally apply to both people and animals. If an animal enters a property without the owner's consent and causes damage or disruption, the owner may take legal action against the person responsible for the animal, such as the animal's owner or handler.
