Answer:
A Lion and a Pig.
Lions cannot purr, but roar instead. This is mainly due to the structure of the bones in the throat, as the hyoid apparatus is not completely ossified (turned to bone). One of the hyoid bones supporting the voice box, or larynx, is replaced by a 15 cm long elastic ligament, which may stretch 20-23 cm. This creates a wide air passage. This produces vibration, which makes the lion the noisiest big cat, with a call reaching 115 decibels.
A pig squeals at 115 decibels.
