Did Jehovah transform the firstborns of Egypt into cats?

Many of the plagues God sent upon the Egyptians involved crazy miracles like turning the Nile into blood or turning sand into gnats. Are there any interpretations that say that the final curse (death of the firstborn) involved the firstborn sons of Egypt being transformed into cats? Is it possible to interpret the Hebrew verb "to slay" as "to turn into an animal"? It's not inconsistent with the rest of the plagues of Egypt, and the Egyptians were known for worshipping cats after all...
