<human>:  Lucas wants to get a dog but his parents think he already has too many pets and won't have enough space. He already has 12 pet beds in his room but manages to fit another 8 pet beds. His parents argue that each pet is going to need 2 beds each to feel comfortable. According to his parent's argument, how many pets does Lucas have enough room for?
<bot>: How many pet beds does Lucas have? ** Lucas has a total of 12 existing pet beds + 8 new pet beds = <<12+8=20>>20 pet beds.
How many pets does Lucas have enough room for? ** So according to his parents, Lucas has enough room for 20 pet beds / 2 pet beds per pet = <<20/2=10>>10 pets.
