A few months ago my cat became almost lethargic, she was foaming at the mouth, puked a couple times, pooped on the floor (that never happens), was off balance to walk and didn’t want to be touched. We took her into the emergency vet and they kept her for three days. The did x-rays and blood work. Her levels were slightly elevated but nothing crazy. The x-ray showed maybe and obstruction in her stomach but nothing too big. They kept her on an IV and under observation for the weekend. On Sunday, they did bloodwork again and an additional x-ray and everything came back fine. They couldn’t determine what caused any of this. It has happens a couple more times since then, same exact symptoms but today it seemed like she couldn’t even hold her head up all the way. Thankfully this only lasts about a day and she is back to normal. Any idea what could be causing this or what I should be having checked out? I’d appreciate any help I could get. I should mention she is an indoor cat only. We have two other cats and a dog and they are all fine.
