Update -- I just did the enema and she definitely has a big ball of poop up there. I tried to use my finger to gently break it up after inserting the soapy water, but wasn't able to get much; however it did feel dry inside the blockage. I'm going out to get MOM.
I'm encouraged the she still acts fine, other than straining to poop.
