Chattanooga's two largest animal shelters are overcrowded and taking on more animals as summer officially begins.

The summer is often the busiest time of year for shelters like McKamey Animal Center and The Humane Educational Society for several reasons: it's a transient time with many people moving and going on vacation, it's breeding season for cats, there's not as many adoptions and the 4th of July holiday.

The two shelters are combining efforts to prepare for the rush of animals by hosting a pre-emptive Adopt-A-Thon Saturday, June 27 with the goal of adopting out more than 200 animals.

The two shelters have more than 800 animals in their care.

The inaugural MAC & cHESe fest lasts from 9 a.m. – 9 p.m. at McKamey (4500 Access Road) and HES (212 N. Highland Park Avenue). Dogs cost $24 and cats cost $12.
