hi all this is fredrick leafy (as named by a 4 year old) we have owned him for about a month now im am wondering if anyone can help with his age we got him off a friend of a friend who said he has had him a couple of years now my main concern is that he could be old and not have much life left which will upset my 3 boys. I read they can have short lives any hel is appreciated and if there is any other ways of telling age just by looking at him thanks all
