My cat is lethargic from Cerenia. When should I call emergency vet?

If this has been going on for more than a few days it might be better to see an emergency veterinarian today, however if the symptoms are more recent you may be able to wait. If Greta's gums seem pale or she is having trouble breathing, or if she has a history of other medical problems it would also be better to have her seen today. Otherwise I think you can probably wait until tomorrow. Ultimately these symptoms are somewhat vague and can be a sign of a number of problems so you should go with your gut.

I'm sorry Sam is so sick! Excessive drooling and lethargy are side effects of Cerenia, and those certainly can be causing the symptoms you are seeing now. I would monitor him for now, and watch out for additional side effects such as fever, convulsion, panting, and muscle tremors. Should you see any of those signs, I would rush Sam into an ER vet immediately. Otherwise, wait until the morning to get the blood test results. Just to add, I'm always an advocate of seeing a vet just to be safe. In my opinion, it's best to be safe than sorry, and if you are very concerned about Sam, it's certainly find to take him into an ER vet to get checked out. I hope this helps and he feels better soon!

Batman likely does not feel good and could even be in pain. Just like people, there are many conditions that can make pets feel sick. This could range from bacterial over growth to intestinal blockage. Also like us, diseases are best addressed early and this may result in a better prognosis. I recommend to have him examined by the veterinarian today. The doctor will need to learn the underlying cause in order to give appropriate treatment. Bring in a stool sample in case the doctor needs to test it. Batman could even have something like a broken bone or a back injury. I hope Batman starts feeling better quickly! Please feel free to post any additional questions!

It's difficult to say whether he needs emergency treatment without fully knowing his current condition. If he is still eating and drinking normally, then this would be an encouraging sign. It would also be good to know if he is still walking/running around occasionally. If this is the case, then I wouldn't consider this an emergency, but would recommend you take him to the vet tomorrow during business hours. If Drake is not eating and drinking, then I would be concerned of a more severe disease and would recommend taking him to the emergency clinic. The staring into space could indicate a few different things. It could indicate that he has a fever from an infection, a metabolic disorder, or a primary disorder in the brain. It could also be completely innocent, so I wouldn't worry too much until a vet does a good evaluation of him and comes up with some more answers. I hope that helps and Drake gets better soon.

Poor Alvin - it sounds like he is not doing well, especially if he is lethargic and moving very little. These signs are very nonspecific and can be caused by a number of things, from an injury to a serious infection. I recommend having him seen by a vet right away. It is likely best to have him seen in an emergency clinic, most towns/cities have at least one that is open 24 hours/day. I hope all is well!

Poor Moe! From what you're describing here, I'm afraid he sounds quite sick. Vomiting, not eating, and acting lethargic are always very concerning symptoms, especially since he's been sick for 2-3 days now and seems to be getting worse. Unfortunately, these are very vague symptoms that could be caused by almost any kind of illness, so it's hard to say what might be wrong without being able to examine him and run some tests. I do think that this sounds like a serious, potentially life-threatening problem that shouldn't wait until tomorrow, so I would recommend taking him to an emergency clinic today to be seen. If you're not sure where to go, try calling your regular vet's office - their voicemail message should have contact information for your nearest ER or an on-call doctor for emergencies.

Poor Cooter! If he's beyond lethargic, I think he needs to see a vet now and shouldn't wait until Monday. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck.
