MADISON, Wis. (AP) -- With temperatures expected to soar near 90 Tuesday, a Wisconsin humane officer is reminding pet and livestock owners to take extra care to protect their animals from heat and humidity.

Dr. Yvonne Bellay of the state agriculture department says heat stroke is a very real threat to animals and can be fatal.

The National Weather Service issued a heat advisory for southern Wisconsin for Tuesday afternoon when highs could reach the upper 80s to mid 90s across the state.

Signs of heat stroke in small animals include panting, breathing difficulty, refusal to obey, vomiting and seizures.

Bellay advises livestock owners to avoid transporting animals in heat over 80 degrees and high humidity and to provide well-ventilated space in any enclosure.
