Interspecies Play-dates

So what if pets had their friends over? I mean, like we have friends over? What if they were like our actual children and could just hang out with other animals from around the neighborhood. Would we stop them from hanging out with anything other than their species? Would our cats get in trouble if they started hanging out with dogs? Would there be certain liberal pet owners that would let their pet turtles hang out with hamsters because "this is the 21st century, stop being speciesist"? I mean, if I returned to my home to find that my cat had become bffs with an echidna, I'd probably allow it. Not a spider though. Those are creepy. Later.
