I am planning to transfer my greeks in my garden and am a bit worried about the cats that roam free. have you ever experienced any attacks from cats on tortoises?
Like was said, hatchlings especially could be harmed. Even if not harmed, they are easy for a cat to take off with it to play with. With most cats they just play with the "moving rocks". On the other hand, an adult sulcata could also harm the cat.
