I offered a fresh killed rat to my snake last night and she did the whole grab and coil like she always does (I guess the twitching makes her think it is still alive), but she didn't eat it. I left her in her feeding container over night with the rat in hopes that she would but when I got up this morning the rat was still there. Should this be of concern? How long before I should offer another? And Clarice (her name, "Silence of the Lambs" lol) is about 40 inches, what is everbody feeding theirs that are that size? Thanks guys!
