In Poland, many people have pets like fish, dogs, cats, hamsters, and parrots. The document's author has a hamster and fish, and their grandfather has a dog named Misiek. Last summer, the author went to Kłajpeda in Lithuania and watched a dolphin show. Dolphins are mammals that live in the sea but have fins and tails like fish. They eat fish and like to play, jump, and even play basketball with their trainers. The author prefers safari parks to zoos because the animals are not in cages and live freely in fields and forests.
