Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
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?

### Response:
 ลูกัสมีเตียงสัตว์เลี้ยงทั้งหมด 8+12=<<8+12=20>>20 เตียง
แต่ละสัตว์ต้องใช้เตียงสองเตียง ดังนั้นลูกัสสามารถมีสัตว์เลี้ยงได้ 20/2=<<20/2=10>>10 ตัว
