i once had two red sided escape into my garden, more than a year later a neighbor spotted one of them in his garden apparently looking A ok. it happened more than fifteen years ago before i had my loft made into my reptile room i used to keep watch on my garden pond to see if they came there to feed, it contains various types of newts frogs and tadpoles but if they did i never caught sight of them, no chance of them breeding though as they were both males, my home is Liverpool England i have neighbors gardens stretching away on each side of my home but we back on to a railroad sidings so they had plenty of space to roam in.
