Small one hatchlings to about 300g I feed every 3-4 days. And I can tell they want it. My female spider is today day four and she is out of her cave looking straight at me and demanding food. Guess what I will be doing tonight...

Bigger than that I try every 5-7 days. I have one stubbornly eats on the 7th day no matter what. Bigger about 700g+ every 7 days. I only have one this size and the rats I ordered online (frozen) are a bit small for her so I have been offering one every 4-5 days. No problem. She's enjoying this. I should post a pic she hit one on the side of her feeding box. Here it is, mind you this is rat number two. Apparently she's hungry
