Cerenia injections + question [May. 23rd, 2011|03:56 pm]
Cat Health


Hello. I posted a little bit ago (my post is on the second page) about my cat getting into some ant spray and getting sick. He made a full recovery and was absolutely fine after a day of rest.

However, he got sick again today. I don't think it's related--I have been very careful and just moved into a new apartment a week ago. I haven't sprayed ANYTHING and all my cleaning supplies are safe in cabinets under the bathroom and kitchen sinks. So, I don't think he got into anything. I woke up this morning to the sound of him sounding like he was in pain. He seemed very constipated and (tmi?) his sphincter was almost..dilating or pulsating in waves; right after it did so, that's when he made his painful meow. He threw up twice as well. I took him to the vet about 2 hours ago and right when we got there, he passed a ball of fecal matter, not kidding you, about the size of a golf ball. He didn't make anymore painful noises after that. The vet stuck his thermometer up his butt and said he didn't feel anymore blockage and he should be okay. He told me not to feed him today to let his stomach settle.

The vet gave him an antibiotic/cortisone injection as well as a Cerenia injection for vomiting. I googled Cerenia to see side effects, and apparently the medication is for dogs but is given off-label to cats as well. :\ Not something I'm completely comfortable with, but I guess the vet knows better than I do.

Anyway, the cat seemed a lot better on the car ride home. He sat in my lap and looked out the window the whole time, until we were almost home. Then he passed more stool, this time looser. The vet said his stool would be looser, so I wasn't concerned about that. However, I got him home and he was panting. It's 90F outside and he's an indoor cat so I imagine he wasn't used to being out in that kind of heat. But, I cannot get him to drink water for anything. He found a dark corner of the apartment and he's lying there right now. He hasn't made any more painful meows, thankfully, but I am still concerned.

I'm going to call the vet in a few minutes, but I'm wondering if any of you have had experiences like this with your cat(s), especially the Cerenia injections or anything. Will any of what the vet gave him make him lethargic like this? The vet is bad about telling me side effects and I ALWAYS forget to ask. Thanks.

Digestive issues can be painful. He's probably also generally unsettled from the move.

The cortisone should help him to be hungry. Feed him wet food (with added water) as soon as he can eat again, to help get the digestion working right.

Best to ask the vet about the lethargy, but the panting might have been because he was stressed from the car ride. I just took one of my cats to the vet for her checkup/vaccines, and she started panting on the way home, even though it wasn't at all hot outside. She was fine once she calmed down.

My cat pants when she's in the car, even when it's not hot; I think it's nerves. My other cat has had some pretty bad bowel issues (nothing like this though) and yeah, that can be pretty painful and upsetting. He moped a lot, and your cat may be doing that too, just needing some time to chill and unwind.

I agree with silaren; if he doesn't want water, try watery foods or treats.

Just so you know there are a lot a lot of things that are labeled for dogs only but are given to cats. In my cat only clinic right now I can name at least 5 items that are 'off label': the euthanasia solution, the gas anesthesia, the cerenia, the pyrantel dewormer (I think that one is labeled for horses), the amoxicillin and the metacam pain med (which has just recently been given the green light for cats but we do not use it often enough to have an updated label on it). I know there are more I just can not think of them right now.

And yes drowsiness and appetite loss are side effects of cerenia:


Don't force him to eat or drink, the panting is most likely stress. Just keep an eye on him, Poor kid, make sure he is still breathing and stuff but I would not worry if he has not eaten or drank anything until tomorrow morning. Then if not call the vet. It's possible that he may need to switch to a wet food or give him a little more fibre in his diet. It also possible this may never happen again. Good luck :)
