I'm not kidding. Many times I've been home with the kids asleep and heard meowing. It's happening right now. It's weirded me out, I'd go looking outside for cats to no avail. Only recently did I realise...it's my husband's turtle! I googled it and sure enough it said scientists recently found turtles meow, amongst other things. Do your turtles meow? I'd never heard of this! I really thought I was loosing my mind. It's an adult female eastern long neck. It totally sounds like a sad cat. Creeps me out.
