My cat is a domestic shorthair female cat and will turn one in July of this year. She's usually very active, and enjoys playing fetch with her toy mouse or toy ball. However, since Friday she has been sleeping a lot more and not really playing like her usual self. She still has an appetite, however, she doesn't eat as much during eat meal. She is not hiding out from anyone, and she purrs whenever she jumps on my bed, which to me indicates that she’s not in pain. What could be wrong?

Hello, and thank you for your question. Cats are notoriously good at hiding their signs of pain and illness. Often the only indication is a decrease in energy and appetite. Possible causes could include pancreatitis, systemic infection, gut parasites, or dental or abdominal pain. If her symptoms are not improving within the next 24 hours, I would recommend taking her to the vet. They can perform a full physical exam, checking for any areas of pain or discomfort, and check for fever and dehydration. They may recommend bloodwork and viral testing to pinpoint a diagnosis. At minimum, they can help rehydrate her if she is dehydrated, and offer medications to improve her appetite and comfort while searching for a diagnosis. In the meantime, offer her some other wet and dry food options in case she has just become picky with her food, and monitor her for any vomiting or diarrhea. I hope this helps, and that Oreo feels better soon!
