Why did they say no to turtles? The only bad side to keeping a turtle in there would be that it would outgrow it in a period of a few months. However, lighting it would be a challange... considering you have to have a 5% UVB light on it. Are you looking for something for her to look at or to actually take out and handle? You may want to consider a baby corn snake or a small morph of a rat snake, however I dont know how you or her mother feel about snakes...and she would have to be very careful on handling such. You may also consider raising tadoples into frogs...or just a couple small frogs or something...just a couple ideas.
