I know some people may more attract mosquito to bite, how about cats and dogs? Is cat or dog more attract mosquitos compared with human?
It is mostly genetics and varies from person to person, cat to cat, and dog to dog. For example, my dog and I are not very attractive to mosquitoes, but my sister gets bitten all the time. It really goes by a per case for each individual and there isn't a straight answer for whether cats, dogs, or humans are the most attractive for mosquitoes.
Here is a helpful article explaining some current research on mosquitoes, humans, and pets and who/ what attracts them: Mosquito Magnets
