Without examining Midnight it is difficult to give a diagnosis since lethargy and loss of appetite are vague symptoms common with many different conditions; infections, parasites (regardless of indoor or not), foreign objects, poisoning, spoiled food, injury (fell from somewhere) among many other causes may lead to these symptoms. You should ensure that Midnight is kept hydrated, but if there is no improvement you should visit your Veterinarian for an examination. Regards Dr Callum Turner DVM
Hello, so after I had a party at my house a few days ago, my cat has been very weak, sleeping all the time, won't eat or drink as much as he used to, and breathing rapidly. I tried bringing him to a vet a couple of days ago and they said it was only stress due to the loud music and crowds from the party, and they told me to give him liquid food along with vitamins every hour for a few days. I've done that for a couple of days but it seems like my cat's breathing actually had gotten more shallow and heavy. I'm afraid that the vet misdiagnosed my cat (I don't trust the credibility of that vet, since they're not the one I'm used to go to), do you think there's anything more than just stress? Also if it helps, he's just gotten his first vaccination around last week. Thank you
My cat is approx 18yrs old & had 4 seizures a couple of weeks ago. Vet ran bloods & said nothing found just white cells up a little. Gave Noroclav 50 for week, no fits since but breathing very fast and hard, can’t get comfy & struggles moving about just sleeps a lot. Little food & water. If walks it’s very slow. Lost weight and ribs are poking out.
Rapid breathing (tachypnea) is a respiratory disorder characterised by abnormal breathing that is rapid and shallow.  It is caused by a reduced level of oxygen, mechanical disorders (where the lungs aren’t able to expand as they should, usually due to a build-up of fluid in or around the lungs), and physiological disorders in which the cat’s respiratory centre in the brain is over stimulated.
