The shelter said so far in July it's adopted 24 animals, which is about 10 more than the average month, but it still has roughly 100 animals.
The shelter is only accepting animals on an emergency basis until its capacity declines. Last month the shelter took more than 200 cats to rescue.
Director Elaine Smith said people often don't mind stray animals around until they begin having puppies and kittens. That's when people call them as and ask for them to be removed. She said there is one simple way to help manage this.
"Spay and neuter is the key to being able to have a shelter that is not full all the time, responsible pet ownership," Smith said.
Seizures also continue to fill the shelter.
Despite being crowded the shelter has no plans to euthanize any animals. It's been nearly two years since the shelter euthanized a healthy animal.
If you'd like to adopt from the shelter its adoption days are Monday, Wednesday and Fridays from noon until 6 p.m., and Saturday's 10 a.m. until 2 p.m.
The shelter is located at 278 Poor Farm Road in Kingwood near the Preston High School.
