Answer:
Biologists have tried to distinguish the living features of the living organism from the non-living features as a cellular organisation, heredity material, metabolism, reproduction, homeostasis, sensitivity, growth and development, and adaptation through evolution. 
The cat can is a living organism as cats shows: 
1. Cellular organization-form organ and organ system. 
2. Heredity material- contains DNA as genetic material which is passed on to generations. 
3. Metabolism-undergo chemical process like cellular respiration. 
4. Reproduction-able to reproduce as they can produce the offspring. 
5. Homeostasis- cats are warm-blooded animals so maintain their internal temperature. 
6. Sensitivity- sensitive to nature as they respond to stimuli. 
7. Growth and development- can grow and develop. 
8. Evolution- cats have been evolved from the ancestral group of mammals.
