Philbrook recently kicked off a pen pal program for the museum cats. A bit of connection in the COVID-19 era. If you write them a letter, they write back. That's the deal. The program took off quickly and mail began arriving daily from around the country and around the world. Some from kids, some from adults. Some silly, some quite moving. Some from other cats (kind of). But one recent arrival stood out. The return address on the envelope was a prison. The letter inside was unforgettable.
