tbf even humans mnbn would probably scream at each other across the house to communicate with how loud they typically are sjhdbcjsh but. you have me thinking about them thumping their feet (imagining they have multiple levels to their house) and thumping from upstairs to get the other to come to them or stuff like that. i probably say this because its something we do at my house when its time to eat, with hitting a cane against the ceiling to the person's bedroom and then said person often thumped my feet to say they were coming soon sjbdcjhsb sorry i got distracted with this answer but basically: yes they scream AND thump their feet to communicate across the house :D
