My cat is lethargic, hiding, and not using litter box. What should I do?
I'm sorry to hear that Lily has been feeling so poorly today. As Dr. Melanie mentioned, lethargy and a loss of appetite can be due to many underlying health conditions. Since she seems to prefer laying down, it's also possible that she's experiencing some degree of pain or discomfort. Some of these possible conditions include pancreatitis, infectious diseases (FIV, feline leukemia, FIP, etc.), constipation, kidney disease, liver disease, toxin exposure (did she eat a plant, medication or something else she shouldn't have?), or many other conditions. The fact that she hasn't been using the litter box normally might be a sign that she is dehydrated, even though she's drinking water when it's placed in front of her. At this point, it would be best to take Lily to her vet fairly urgently for evaluation. Your vet will need to examine her and will likely recommend some diagnostic testing, which may include blood work, an ultrasound or x-rays, to get to the bottom of this issue. I hope that she feels better soon!
