Why is my indoor/outdoor cat lethargic, gagging, and acting strange?

I would recommend keeping a very close eye on your cat for the next 12 to 24 hours. When cats are free to roam outside they are more prone to getting in fights and ingesting something toxic. If she does not eat this evening or tomorrow morning and she is still acting lethargic and I would recommend taking her in to your vet to be checked out.

Lethargy can be a sign of many different diseases. I am not sure of his age but he should be examined by a vet to determine the cause. He could have an infection, musculoskeletal issue, kidney disease, liver disease, diabetes, thyroid issue, etc. Your vet can run some lab-work and take x-rays, if needed, to help diagnose and then determine the best way to treat. He may need an antibiotic, anti-inflammatory, or other medications, depending on the cause. Hope he feels better soon!

These symptoms are definitely of concern and most likely a sign of illness and not depression. It is not any fault of yours, but he does need to see a veterinarian to determine the cause of his illness. They may recommend running bloodwork to check for signs of systemic illness such as kidney disease or infection, and may want to test his for Feline Leukemia and Feline Aids since he was an outdoor cat before he came to you.

Poor Meredith! Lethargy is a very general sign of illness in cats, and it can be caused by systemic illness, infection, inflammation, or injury. Given that she is eating and drinking as normal, I would monitor her for now. If she is still lethargic in another 24-48 hours, I would have her seen by a vet. Should she stop eating or drink, or develops other signs such as vomiting and diarrhea, I would have her seen by a vet right away.

Unfortunately lethargy is a very common sign of many things include systemic illness, infection, injury, or inflammation. t's good that Gizmo is seeing a vet tomorrow. Keep him warm and comfortable, and keep him indoors for now if he's allowed outdoors. Best of luck.

Just like humans, pets can get sick for many many reasons. It's possible he's fighting a virus, that he ate something he shouldn't have or that his stomach hurts. If he is lethargic beyond 48 hours, if he is not eating or drinking as normal or if he is getting worse, have him examined by the veterinarian.

It's hard to know exactly what could be going on. She may have gotten hypothermic, she may have had a seizure, she may have been feeling bad before going outside and been looking for somewhere quiet. Regardless, since she's vomited a few times and has been lethargic for 10 hours, I would consider taking her to an emergency room for evaluation tonight. If she still seems very sleepy tomorrow, she should definitely be evaluated. Good luck to you both!
