Were there any animals or pets on the Mayflower voyage in 1620?

Although there was no livestock on board the Mayflower voyage in 1620, there probably was the usual cat or two to keep the rat populations in check.

We also know that at least two passengers brought pet dogs, a mastiff and a spaniel used to hunt during the first winter months in America.

Most historians believe there were surely more, but these two were the only ones mentioned in journals.
