Snopes says:

There is no evidence, outside of second- and third-hand social media gossip, to support the notion that Haitian residents of Springfield, Ohio, are eating people's pet cats or their parks' waterfowl. The only alleged evidence in support of the former actually depicts an American in a different city. The alleged evidence of the latter stems from a single picture apparently taken in a different city.

For these reasons, and because Springfield officials deny the validity of such reports, the claim is "Unfounded."
