If any animal is found to be confined without adequate food and water, an agent may as necessary enter into any and upon any area or building where such animal is confined and supply it with adequate food and water.
An agent may lawfully interfere to prevent the perpetration of an act of mistreatment, neglect, abandonment, or cruelty, pursuant to part 2 of article 9 of title 18, C.R.S., which act occurs in his or her presence.
Any agent may lawfully euthanize or cause to be euthanized any animal in his or her charge when, in the judgment of such agent, and in the opinion of a licensed veterinarian, the animal is experiencing extreme pain or suffering or is severely injured past recovery, severely disabled past recovery, or severely diseased past recovery. In the event a licensed veterinarian is not available, the animal may be euthanized by an agent if, by the written certificate of two persons, one of whom may be selected by the owner if the owner so requests, called to view the animal in the presence of the agent, the animal appears to be severely injured past recovery, severely disabled past recovery, severely diseased past recovery, or unfit for any useful purpose.
