My Cat
I wish I were a cat. if I were a cat I <s>won't </s>wouldn't have to worry about a thing in the world, I would have lived my life in a family that pets (also pet, without s... you have used family as a plural noun later in this text.) me and feeds me <s>every day </s> everyday. even though I would bite them and leave my fur on every surface in the house, my biggest fears would be <s>to</s> not to be stepped on or getting a bath.
I wish I were a cat so my family would shower me with their unconditional love and I would still wake them up in the middle of the night for no reason.
life would have been much simpler if I were just a cute cat, thinking about how to ignore everyone and not getting attached to them, not caring about how they think of me or being quick to forget and forgive about how they treated me when they were angry.
About the last sentence, "or being quick..."...I'm not sure if it is right or wrong .. your sentence is simply too long :D
By the way, I hope you will have your wishes fulfilled.
