I'm so happy I don't have to worry about my food running off the plate. Although it would be a little extra exercise chasing it and I would Chase it.It really helps to have my own lobster roach colony. If you had to buy dubias at the pet store then this would cost a fortune. It also eats the tunip greens and zucchini and squash but loves roaches. These are climbing roaches so Newman has to catch them fast.
