Of Cats and Tea

I made a promise to myself not to buy too many products from David's Tea because I have enough stuff from them and too little space to store them. I can buy more of their teas, but their accessories might end up cluttering the flat, like so many things do. And just when I thought I could behave, I learn on their Facebook page that they have a Feel-Good Collection which includes a cats colour changing perfect tea mug and cats infusers, one aquamarine, one azure blue. For a cat lover like me, this is shameless teasing (sorry for the pun). I guess I could buy the infusers, they barely take any space, but the perfect tea mug might just be one mug too many. Although I could give the mug as a gift to someone else and make this person feel good. But then I know I'd buy one for myself anyway. So I am having a terrible dilemma. Why am I such a sucker?
