IL SB2203

Amends the Humane Care for Animals Act to define "adequate shelter" as shelter suitable for the animal's species, age, and size that provides protection from weather, injury, and extreme temperatures, includes proper lighting and sanitation, and for dogs and cats must include a solid resting surface that can be maintained sanitary.

Defines "adequate space" as sufficient space allowing each animal to stand, sit, lie, turn about, and make normal body movements comfortably, and to interact safely with other animals.

Requires animal owners to provide adequate shelter, adequate space, and protection from weather in addition to food, water, veterinary care, and humane treatment.

Establishes regulations for tethering dogs outdoors, including minimum 10-foot lead length, prohibition on leads exceeding one-eighth of the dog's body weight or tow chains, requirement for proper harness or collar, and restriction from reaching neighboring properties or public areas.

Makes violations of owner duties a Class B misdemeanor for first offense and Class 4 felony for subsequent violations; violation of tethering requirements is a Class B misdemeanor; courts may order psychological evaluation and treatment for violators and must do so for juveniles or animal hoarders.
