By picking her up when her tail was "bent" upwards to put her in the tub, you probably interrupted her "release", but maybe it was just gas she was waiting
for. No big deal, doesn't mean she's constipated...in fact, with watery stool already expelled, it's unlikely that she's constipated at all. Constipation usually
results from the stool taking too long to be expelled resulting in more water being absorbed, making the stool too dry & hard to expel. For future reference,
I wouldn't have picked her up as you did.
