Monday:
Consulted the vet. Turns out there's a small risk of rabies. So they have to be quarantined, for 45 days. The quarantine zone is right outside of my home office. I have a fun night ahead of me watching youtube videos of cats with rabies and studying the symptoms so I know what to look for. It's very interesting and unsettling at the same time.
