A tiny gnat, invisible to me, must have fallen close to the droppings and tempted the fish.
Bat droppings are similar to small mammals but on closer inspection are very crumbly due to the insect contents.
Try encouraging your rabbit by putting some of his or her droppings into the box or try using timothy hay or treats.
Just dining on too much fresh, rich grass can make even an otherwise healthy bunny produce too many soft droppings.
One night we left droppings splattered around in my grandmother's penthouse while elephants scratched mom 's favorite pink Cadillac.
