Why is there a limit of pets per residence in the Animal Control Bylaw?

A limit on the maximum number of pets per household is common among Animal Control Bylaws in municipalities.

A maximum limit of five cats and dogs in total per residence is permitted in the Town of Ponoka (unless the property is occupied and operated by a licensed kennel operator in accordance with a development permit under the Town's Land Use Bylaw). See Part 5, #19.
