In modern life, pets have growing role in human society. They live with us and are everywhere in our vicinity. For a pleasant coexistence with them, we need to take proper care for them (hygiene, space…) and take care for their health, which is connected with offered feed. It should be adjusted to age and physiological state of animals. As a lover of small animals, I decided to explore a bit more details of need for a variety of nutritious substances for pregnant cats and kittens. At the time of pregnancy and lactation cat's nutrition requirements increased and also the nutrition requirements of kittens are different as for adult cat. In addition, at market we looked for the food for pregnant cats, lactating cats, adult cats and kittens and according to their composition, compared them with each other and with the requirements. We were also interested, from which components are these mixtures compound. We found that according to the needs of cats, they differ in analytical composition at different stages of life. The declared content is in accordance with the requirements.
