I need poop help!

ladysingstheblues

He had a big poop this morning.  It was black and green with mucous.  Not hard but not runny.

His second poop was much smaller, but the same colors.  This time it was even more mucousy.

He seems fine.  He had a lot of blueberries last night, but he has blueberries frequently and his poop never looks like this
