Well, it literally wants you to pet the animal to have them.

This is boringly adorable. You have to pet the animal you're gonna encounter and it's not just a normal pet, it varies to each animal how you would pet them. Having the wrong way of petting will cost you energy and you have to play ads in order to keep playing once the energy runs out. This is not really very interesting, but I got to hand it to them. The animals are so cuteee. The home as well as cozy to look at.
