I started writing this when I was asked to write about a hobby. So, I thought, what's my hobby! Well, hobbies are generally activities undertaken for pleasure, and usually in one's spare time - which actually means you don't have any free time if you have a hobby. Indeed, I often find a lack of free time and one thing that contributes to that situation is the fact that we have multiple cats.
Having multiple cats are wonderful - it multiplies the joy of having a cat. It also multiplies the work though, taking up lots of my spare time. So, I reckon caring for multiple cats qualifies as a hobby!
