I first learned about the Pickerel Frog after my yellow Tabby could not resist sniffing the little guy that was hiding beneath a clump of Tiger Lillies. The cat quickly retracted with one eye shut tight. I hurried to do a lookup to an online source and learned, just as I had suspected, that the Pickeral Frog, when under stress, secretes a substance that can be toxic to other frogs as well as irritating to eyes, mucous membranes or broken skin. Hand washing is advised. After wiping with a cold water compress, the cat’s eye quickly returned to normal. I look forward to another Summer when the little visitors return. P.S. Glad to have found a site with other "frog lovers"!! We have several varieties here in RI. Some swim in our small pond, others frequent the gardens, and still others hang out on tree branches filling the early evening with song!!
