Here it varies depending on town or city as well. MOST places allow 3-5 dogs and unlimited cats (as well as unlimited caged animals & fish), but again it really varies depending on where you live. Some places in NY are starting to have a limit on cats and some are even starting a leash law for cats as well. I have a limit on cats where I live but that is because I live in a trailer park & I have to obide by the parks rules but anywhere else in my town it is unlimited, the towns limit for dogs is 4, I'm at my max. lol.
