Regardless, you should visit your Veterinarian or an Emergency Veterinarian to examine Gizmo since she should be eating and drinking normally after this routine surgery and the ‘seizure like’ activity is also concerning; the moderate increase in respiration may be due to discomfort from surgery or due to something more serious.

Two days is still early days for treatment but you should start seeing some improvement in the next day or so, I would say to give it the weekend and if there is no improvement in Jinx’s condition you should return to your Veterinarian on Monday for another examination. Improvement in an animal's condition, especially with antibiotics, can be delayed in most cases so unless your Veterinarian said specifically ‘you’ll see improvement over the next 24 hours’ or something similar you should give it three or four days at least.

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
Chausies are bred to be medium to large in size, as compared to traditional domestic breeds. Most Chausies are a little smaller than a male Maine Coon, for example, but larger than a Siamese. Adult Chausie males typically weigh 15 to 25 pounds. Adult females are usually 15 to 20 pounds. However, because Chausies are built for running and jumping, they are long-bodied and leggy with medium boning. The torso is deep-chested with flat sides. The ears are broad, tall, and set high on the head, about two fingers apart. The cheekbones are striking—prominent, long, and angular—and the eyes are flattened on top and form a half oval below.
Any changes in breathing should be concerning, you should keep a close eye on Lucy to see if it passes; if it seems like she is having difficulty getting enough oxygen or her gums are pale you should visit a Veterinarian immediately. Infections, laryngeal disorders, airway obstructions, tumours, poisoning, anaemia among other causes may cause respiratory difficulties. Regards Dr Callum Turner DVM
