possibly, ive seen people feed sulcatas apples as treats but i really dont know if its good for them since apples have a high amount of acidity in them
Agnieszka, I have given my adult torts a small piece of apple or pear a time or two. But it would really be best to feed them flowers a treat instead of fruit, as fruits have far too much sugars which 1) cause runny stools, & 2) get them hooked on sweets (just like us) causing them to become picky eaters. But as a once in a few months treat it should not hurt them. Just make sure NO SEEDS they are toxic.
