Luca and Lark are two determined kittens when it comes to chasing their toys.

And they’ll catch them, if Caitlin McAuliffe, their foster, allows it.

McAuliffe is a cat foster with the ASPCA. She and her husband have given a temporary home to more than 100 cats in the U.S. and England.

“The idea that me doing this will actually save an animal’s life,” McAuliffe said. “It’s a really powerful thing.”

It started across the pond. The couple knew they’d be moving stateside and didn’t want to put a cat through the trauma of a big move.

Instead, they fostered Kit and Kat.

“I was like, ‘This is amazing. I love having a cat,’” McAuliffe said.

McAuliffe temporarily gave a home to cats when she and her husband lived in Florida.

They failed the temporary part a few times, making permanent additions to the family.

A year and a half into their time fostering in New York, the ASPCA asked them to take in kittens, Harmonica and Harp, with ringworm.

“We got to keep the kitten that we fostered for longer than we typically would because they had to clear ringworm,” she said. “So we got to, kind of, bond with them a bit more.”

That was about a dozen kittens ago.

McAuliffe gives them medicated baths, ointments and other medications and keeps their spaces clean.

“You may get this little crusty mess of a kitten,” she said. “And then as you’re doing the treatment, you know, you’re seeing that hair start to grow in and you’re seeing those little lesions start to go away. It’s just really special.”

They give the cats the care they need, along with respite from overburdened shelters.

“It is really nice to, you know, be their person essentially for these really important weeks in their lives.”
