Discussing her new Just One line of pet products with the press, Katherine revealed that bedtime at her house can take a while! As a mom of two daughters and seven other kids of the four-legged variety, she likes to give each one special attention. First she tucks in her girls, 4-year-old Naleigh and baby Adalaide, who turns 1 in April. Then she takes her seven dogs through their own nighttime ritual.

"I literally put each one to bed and every one of them gets hugged and kissed before they go to bed," she laughed in a recent interview. "It sounds absurd because there are some nights where you're like, 'I'm exhausted!' but there's never a night where I don't want that time with them."

With Just One, she has channeled her love of animals to ending animal abuse, where a percentage of the proceeds go to help programs that foster, train, neuter and rescue animals.

"It's been an interesting and long process developing this and it feels so rewarding and exciting that it's coming to fruition," she explained.

Recently Katherine helped fund two transport flights to send animals from Los Angeles kill shelters to North Shore Animal League on Long Island, New York, which is known as the world's largest no-kill shelter. While she understands not everyone can afford to help the way she can, "If every person does one small thing to help one pet that could be the solution to the whole problem."

Although Katherine bought her first three dogs - miniature schnauzers - because "I just didn't know any better," since then, she's been turning to rescues. "One dog I rescued from Rhode Island while filming 27 Dresses. I love older dogs. I think people don't realize how much easier they are than puppies. I think they just sense or know that they have you to thank."
