this would be very handy for yukkuri, the desire to refreash is herditary to all liveing being, yukkuri have the misfortune of getting pregnant anytime they want to have sex, where humans and animals do not. this device allows yukkuri to refreash without the worries of the resulting little ones
Of course that still doesn't solve the problem if the Pet mistakenly assumes she can force her owner to adopt her partner without even asking.
But I bet this device isn't necessarily aimed for that kind of pets, but for those that want to refresh but are respectful of the "no stray adoption or little ones making without mister's permission."
