What is a group of cats called?

There isn't a formally recognized group of cats called "a [blank]". To give you information, I need to know what word fills in the blank. For example, are you thinking of a:

  • Specific breed? (e.g., a clowder of tabby cats, a pride of Maine Coons) - In this case, I'd need the breed name.
  • Group based on location? (e.g., the alley cats of Brooklyn) - I'd need the location.
  • Group based on behavior? (e.g., a gang of feral cats) - The descriptive term would help.
  • Fictional group? (e.g., the mischievous cats of Narnia) - The fictional work would be needed.

Please provide the missing word so I can give you relevant information.
