I cut down a lot. Mostly due to not having the funds or time/energy to take on a lot of pets. I got 3 smaller fish tanks now, all native, don't require heat, keep it natural with plants, fewer waterchanges etc. But instead of pets I replaced it with plants. I am sort of a plant nut right now so that takes a lot of my time, money, energy. I also got a small pond that is a big responsibility too. Atleast I know what I can properly care for, some people don't.
Nothing bad with having your house a zoo or jungle. When I nurture my plants I feel a sense of calm and satisfaction.
