i think whenever a minor creature/animal is added it should be able to be your pet,like we have dog,wolf,horse,and raptor but why not the (RAT) and you can have the usual animal mounts you,but if you have the rat with you and maybe high rat/ratkin like you get special interactions,Example - rat with you and submitting to the rats with high like results in a big group of rats taking you for a joy ride,while submitting to the wererats with the rat and high like you get a very degrading gangbang from a few wererats while some rats also take advantage of you
