Date Time National Pet Desexing Month: Casey Recognising National Desexing Month, Council is reminding Casey’s dog and cat owners of the importance of responsible pet ownership. Having a pet can be a wonderful addition to your family, and being a responsible pet owner means ensuring your pet is exercised, trained, microchipped, desexed, registered, and most of all cared for and loved. Tips on responsible pet ownership: Ensure your pet is registered with Council and your registration details are up to date. Under the Domestic Animals Act 1994, any dog or cat which is three months of age or older needs to be registered with Council and paid by 10 April each year. If you haven’t yet registered your pet contact Council or register your pet online.
