Studying the anatomical differences of the respiratory system of both rabbit and cat offers a valuable evidence for clinicians regarding the possibility of utilization as models to human being studies. This work was conducted using clinically healthy twenty five for each domestic cats and White New Zealand rabbits, of different sexes and weights. Different techniques were applied from drying, fixed, specimens as well as histological and histochemical studies. The nostrils of rabbit were slit like opening with complete deep cleft philtrum while the cat nostrils were semicircular with shallow grooved philtrum. The nasal septum of rabbit was three layers while in the cat was only single layer. The nasal septum of both rabbit and cat showed high level of acidic mucins in the lining epithelium and low level of neutral mucins. The corniculates and cuniform cartilages were appeared in the larynx of the rabbit and disappeared in the cat
