we vacationed for thanksgiving week and left squirt with a close friend, who said she didnt feed vegetables the entire week because he/she wouldnt eat them. (usually i leave the veggies in there daily until he loses the stubbornness and eats em)
as for mistaking the black thing as something else (im pretty sure it isnt a penis after looking at the pictures, also the cloaca is definitely not a male's), i am assuming (not to be gross or anything) that part of the stool was sticking out until release...

still, the cloaca area looks a little bigger than usual and i am worried. im trying to convince myself squirt is only constipated and a little warm water+more fiber will let the rest do its work. i will keep you posted. thank you for your help!
