My cat is shaking, very sleepy, and not himself. When to see vet?

I would err on the side of caution and get them seen today if you can, tomorrow, especially if they don't seem better. The vomitus looks like a hairball to me, but it's hard to tell. They may have overeaten, but unless that's something they already do, given the opportunity, I don't see that being as likely as something else, possibly getting into something they shouldn't have. Your vet will do an exam, possibly bloodwork, and maybe more//other diagnostics depending on what they find. Based on these results, your vet will have a better idea of what's going on and be able to recommend a treatment plan if needed.

Hi there, It sounds like Leo may have hit his head and may be having small seizures. I would recommend you take him to your veterinarian as soon as possible for an exam, especially if he's acting like he's in a coma. I hope that helps and thanks for using Petco Pet Education Center, formerly Petcoach.

Considering his age and the signs you described, I would be concerned and recommend an immediate check up. Differentials are many, from gastrointestinal diseases (infection/inflammations often dietary related) to any disease that can spread systemically (causing lethargy for example) like infection, and anything that can cause pain/discomfort. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

It could be Shaky is in pain, either from his back or hips. Rest him tonight, keep him indoors if he's allowed outside, and watch him. If he's still acting this way in the morning, have him seen by a vet. Do not give him any human pain medications. Many are toxic to cats, and are fatal if given. Best of luck.

Poor Lilmam. It could be that he has a respiratory infection causing his symptoms. I would call his vet today to make an appointment for him. He needs to be checked out to diagnose for sure what is causing his symptoms so he can be treated. Best of luck.

Thank you for submitting your question regarding Mumu. I recommend that he sees a veterinarian. He could be painful from some trauma that occurred outside such as a cat fight wound. If this is not the case, then he may have been exposed to a toxin. His veterinarian will examine him and determine how best to help him feel better. I hope this information helps!

You definitely don't need to rush him to the vet now, but may want to take him within the next day or two. It appears that Lenny is coming down with an upper respiratory infection. Early in the infection they tend to feel bad and get more lethargic. The vomiting could also be explained by this general malaise that is felt. Often, these upper respiratory infections are caused by a virus and there is not a specific treatment for it; so the need for medication usually depends on the severity of the infection. Since Lenny is obviously not feeling well, he could have a high temperature and a vet may prescribe medication to make him feel better. They may also prescribe antibiotics if they are worried about a bacterial infection. I think it's fine to wait until tomorrow and see how he is doing. If he still feels bad, or seems worse, then it's best to have a vet evaluate him. I hope that helps and Lenny feels better soon.
