Cat gets ready to celebrate Mardi Gras, one of the Many 2021 Pet (Mostly Cat) Holidays.

Complete list of 2021 Pet (Mostly Cat) Holidays


A complete list of 2021 pet holidays is essential for those wishing to celebrate cats this year. At Paws News for Cat Lovers, we focus on cat tourism and events, cat news, and lots of other cat stuff. Therefore, we felt we would be remiss if we did not bring you a complete list of special cat days in 2021. While many places may not be open in person due to the pandemic, there is bound to be a flurry of online activity surrounding pet holidays in 2021.

The complete list of 2021 pet (mostly cat) holidays include well-known celebrations like National Cat Day on Oct. 29, the Fourth of July, Halloween, National Black Cat Appreciation Day on August 17, and February’s Feline Fix by Five Appreciation Month.

We also include January’s Answer Your Cat Question Day (January 22), Change a Pet’s Life’s Day (January 24) and National Plan Your Vacation Day (January 26).

The list is comprehensive, including National Disaster Preparedness Month (September), Adopt-A-Shelter Cat Month (June) and Happy Cat Month (September).

This list serves as a great guide for writers, bloggers, photographers, videographers, or event planners that are looking for a way to gain attention in a fun way. We encourage you to bookmark this list, and keep it handy, for your reference in 2021.
