A flickr friend Susan (Tiger's Lair) is a librarian at Ormond Beach (FL)Library; she's a cat lover and has several great cat groups on Flickr. Here's her comprehensive report on cat holidays through the year, starting of course with January 2-
Happy Mew Year for Cats Day. A few other cat holiday highlights are:
February is Pet Dental Health Month
April is National Pet First Aid Awareness Month and
Prevention of Animal Cruelty Month
and as I believe was pointed out on these pages last spring...
April 28 is
Hairball Awareness Day .
