As the weather warms, the wolves have been spending more of their time sleeping during the day. They have not begun to shed their winter coats and even daytime temperatures of 50 degrees make for uncomfortable conditions. Since wolves have a fur coat instead of sweat glands across their body, they avoid overheating by remaining inactive or by panting to evaporate heat off their tongue. Today, all wolves are sleeping when staff enters the enclosure. Lucas got up and was observed limping on his front left leg, but that diminished during the staff visit, another sign of being 9 years old (Mackenzie, Lucas and Lakota turned 9 on April 24th). All wolves were calm with good interactions.
