I wish they would increase the number of pets allowed on the inside and outside of your homes, the dorm should stay at 50, but big castles and other homes should be at like 200 on the out side and 100 on the inside or more depending on the size of the castle or house. Selling pets is not profitable cause it cost you more to raise them and hatch them. Then what you get to sell them for gold. maybe sell a pet eliexer that allows additional 50 pets more in your yard to be turned loose is an option.
