"he'll be real 'durable'"

A 7 year old patient came to therapy looking distraught. I asked her if she was ok. Her mom said, "Well, she had a real upsetting thing happen this morning. Our cat died." My patient shakes her head yes looking real sad. She starting therapy by jumping on the trampoline and said, "Well. We'll get a new cat, and he'll be real durable." After explaining to her what durable meant, I realized she was trying to say adorable.
