Could be unrelated.
My female had a cycle around 8 weeks ago. She's been a bit off her food as in not as food driven as normal but still hungry until today. She vomited this morning, then ate grass and vomited it up again at lunch walk and is feeling down- lower energy for sure.
I think she had similar issues with diarrhea and no appetite last cycle though I didn't make the connection and thought it was something she ate... it lasted a week or so. I even took her to the vet.
Is this likely unrelated or have people seen similar digestive stuff when their hormone levels drop at week 8 after a cycle?
I have her mom as well, and she goes through a bit of a loss in appetite, less interest in food but no real stomach upset or vomiting. They also start "denning" under the deck or rocks, etc.
Curious if this is at all common. Could be a completely unrelated cause.
