Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. It is possible that Bonnie ate something that caused these symptoms. However, regardless of what caused these symptoms, I would recommend having a veterinarian examine her. She may be dehydrated and in need of fluids, which the veterinarian can evaluate her for. I would also recommend having her blood tested to see if there are any abnormal values that need to be addressed. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please take the time to mark this question as helpful or not as it helps us to improve on the quality of our answers to other pet owners. Thank you kindly!
