Ok I don't know where in NY you live but I watch Animal Planet all the time and there is one Rescue NY,you know animal control I don't know the exact name of the show but it is NY.They said numerous times the limit on pets were four.These Animal cops were going in and rescueing animals from Apartment living and they let them keep four and took the rest.Numerous times I watched this program and numerous times they said four.I know in Illinois depending on the size of your home and your land you can have as many as you want.Just depends on the size of the property the animals are in.Just call your animal shelter (from a pay phone) and ask what the limit is.I would bet you would be suprised on the limit.Also keep in mind they might say the limit is only three for larger size dogs.You have small pets.heck combine them all and you would get a large size dog
I wouldn't worry too much as other said if someone does come a knocking ask to see a search warrant.Then go from there.Good luck!
