Fish are better than cats or cats are better than fish?

Fish are better than cats or cats are better than fish – this is not an easy question.
There are many aspects that point at fish or cats. For example if we take a look from a feeding point a view fish are better because they have many ingredients that are necessary for our proper functioning as phosphorus. Cats losing completely in this way of thinking, because no one (or almost no one) eats cats I think.

If we look at this question from the other side we can say that you don't need to walk with your fish, on the other hand keeping several cats in a small glass box will get you in trouble with the RSPCA (the Royal Society for the Prevention of Cruelty to Animals).
There are many other aspects that are against cats, thus have you ever seen a fish stuck up in a tree? Also you don't need to take your fish to the vet for shots and the fish is unable to leave its hair all over your sofa. We can multiply examples - Unless you have a piranha and you stick your hand in the tank, your fish will not bite or scratch you. For sure transporting your dog or cat in a sealed plastic bag is a undoubtedy bad idea. And - last but not least - when your fish dies, you can unceremoniously flush it down the toilet.

It seems fish are much better than cats, but there is one thing that makes cats indispensable – they catch mice in a far, fat better way than fish. Besides that we can take a cat on our knees and stroke them, many people like this because it makes them calm.
As you see sometimes cats are better than fish and vice versa. I leave the decision which one is the best up to You.
