The best thing you need is pretty obvious-cat.Firstly, cats are soft and fluffy. They help you to get rid of diseases.For instance headache or stomach ache. They are pretty calm creatures. They bring lots of positive mood and take negative energy or thoughts away. Cats will never betray you , they are reliable and kind(unless you have got a cray one but its fun then)So..I recommend everyone to buy cats, this is the best thing yet invented to support you and bring lots of happiness and love)))
