Wyo. Stat. § 4-10-409 (2026)

(a) A trust may be created to provide for the care of an
animal alive during the settlor's lifetime. The trust terminates
upon the death of the animal or, if the trust was created to
provide for the care of more than one (1) animal alive during
the settlor's lifetime, upon the death of the last surviving
animal.

     (b) A trust authorized by this section may be enforced by
a person appointed in the terms of the trust, trust advisor,
trust protector or, if no person is so appointed, by a person
appointed by the court. A person having an interest in the
welfare of the animal may request the court to appoint a person
to enforce the trust or to remove a person appointed.

     (c) Property of a trust authorized by this section may be
applied only to its intended use, except to the extent the court
determines that the value of the trust property exceeds the
amount required for the intended use. Except as otherwise
provided in the terms of the trust, property not required for
the intended use shall be distributed to the settlor, if then
living, otherwise to the settlor's successors in interest.
