Cats poop is yellow

Hi! My cats poop is solid and the exterior is brown, but this inside is yellow in color. I'm feeding her purina one dry food and there are brown bits of food and yellow bits of food. Could it be related to this? Thank you.

Sounds like mommy's poop. As long as its not runny, I don't think there is any reason to be concerned.

It was runny last month but antibiotics and switching food did the trick. It's totally solid, the only reason I noticed today is because the pieces of poop were smaller and broken up compared to usual. I did introduce some wet food to her diet so maybe that's the culprit too.
