It was Sunday so I didn’t have to go to school. I woke up late, got up and WENT to the kitchen.
It was strange but I COULDN’T find our cat, Tom, anywhere. The whole family got worried.
“He’s gone hunting,” my YOUNGER sister said. 
“All cats hunt MICE. I read about it in a book.”
“I’m sure he IS SLEEPING in the armchair,” Mum said. But the cat wasn’t there either.
“Look! I HAVE FOUND him!” my little sister shouted. “He’s in the washing machine!” We watched in surprise as the cat got out of the washing machine.
“Come on, kitty, come here. We WILL  GIVE you some milk.”

An Allergy is a hypersensitivity of the body to any substance. This substance can be any chemical ingredient, product, hair, dust, pollen or a germ. Today it is well established that allergens may be substances produced within the body. They are called antiallergenic or autoallergens. They are natural – unmodified tissue proteins that are isolated from the systems that are responsible for immunity. And purchased – proteins that acquire foreign properties against thermal, radiation, chemical, bacterial, viral, and other factors. For example, an allergic reaction develops with glomerulonephritis, rheumatism, arthritis, hypothyroidism.
