Answer:

Human cells do not have the chemical receptors required for attachment by feline immunodeficiency virus

Explanation:

Feline immunodeficiency virus is a virus which causes immunodeficiency in the cats worldwide that is they use the cat as a host to replicate themselves by using their DNA replication machinery.

The feline virus does not affect the humans or they cannot affect the humans and this could be accounted to the reason that human body does not have the receptors which allow the cell to surface interaction between the body and the virus. Since a virus does not get attached to the body, therefore, cannot affect the humans.
