Does the Moon Affect Feline Health?

Wells, R. J., J. R. Gionfriddo, et al. (2007). “Canine and feline emergency room visits and the lunar cycle: 11,940 cases (1992-2002).” J Am Vet Med Assoc 231(2): 251-3.

The aim of this study was to determine the frequency of canine and feline emergency visits with respect to the lunar cycle. Relative risk calculations identified a significant increase in emergencies for dogs and cats on fuller moon days (waxing gibbous to waning gibbous), compared with all other days.
