The animal crate cooling system comprises a thermal cover for an animal crate and a cold air unit The cold air unit generates and circulates cool air through the crate. The thermal cover comprises a plurality of thermally insulated panels that surround the sides and top of the crate. One or more apertures in the top of the thermal cover allow air to enter and/or exit the crate. The cold air unit utilizes carbon dioxide gas from an attached CO2 cylinder to make dry ice by blowing the CO2 into a mesh basket within the cold air unit. One or more air moving devices may circulate cool air from the cold air unit over the dry ice and through the crate. The air moving devices may be powered by a battery, which may be recharged using a solar panel.
