How Old Is Your Cat?
How old is your cat? It’s useful to understand a cat’s true age in terms of human ages in order to better understand behaviour and to better provide for their needs. Their diet changes from one life stage to another. Behaviour changes, and other needs may change as the cat grows up and then grows older.
