Eating little, small poops?

[Sendra]

Tribble has started eating less and has begun to have smaller poops. The same thing happened around this time of year last time as well and she was cleared at the vet of not having bloat or any other issue that should be causing it. It's happened again, and while she isn't eating much, she is very hyper, happy, and attentive. Her abdomen isn't distended or hard to imply bloat. Could this have something to do with her beginning to go into heat? I heard in the northern hemisphere its from November to May?

I'd be more suspicious of tooth problems. I had that happen with my oldest. Her tooth had a burr growing over her tongue.

She was cleared of any tooth issues via x-ray less than 3 weeks ago.
