Many of us have pets. It is a source of relaxation and has a calming effect on us. Many houses have dogs, while others have birds, fishes etc.
But just having a pet isn’t enough. Proper care needs to be taken to see that they don’t fall ill, or catch a disease. As a result, pet care is a big industry today which provides specialized products for various pets. There are specially formulated dog foods for various species, and special medicines to be added to the water in aquariums. Again, one sort of medicine cannot be used with all sorts of fishes, so there are specializations there as well.
