I am asking because I see so many people marked as hoarders with animals now a days. For me, dogs should be a 1:1 ratio to people in the house, cats can be a 2:1 (2 cats per person), and everything else all depends on space and age really.
How many pets is too many in your book? I have a friend who lives with her sister and her boyfriend and they have 7 cats. Now that sounds like a lot but their place never smells and you really wouldn't know they had a ton of cats if you just did a walk through. At the same time, a woman down the street from me has 7 cats and it kind of smells around her house. :/
