Keeping cats indoors all the time was not possible—nor was it even a goal—until several important 20th century innovations: refrigeration, kitty litter, and the prevalence of spaying and neutering.

Even though these changes to our modern lifestyle make keeping cats inside possible, biologically, cats are the same as they were thousands of years ago. Their role in our society has evolved and broadened over the last hundred years, but their basic behaviors and needs haven’t changed.

Basic needs for indoor cats are

  • Responsible Pet owners
  • Food and Water
  • Their own space, resting places, cat beds….
  • Litter boxes
  • Scratching poles
  • Perches or higher places to enjoy
  • Toys
  • Some company.

Kitty Litter

Did you know the first clay litter was accidentally discovered in 1947 and then subsequent marketing of the Tidy Cats® brand in the 1960s that litter boxes really caught on. With the invention of cat litter, cats rocketed to popularity as indoor pets.


Pet desexing became available and accessible around the 1930s and again increased they popularity as indoor pets.
