Hello, I no longer have a diabetic cat but thought that maybe I could post this question here since there have been discussions on Convenia. My apologies that it's a long post, but I want to give as much info as possible and ask for any opinions...

Beastie:
Torbie, about 12 years old. Temperamental, gets really nasty when she doesn't like what you are doing. I can restrain and administer liquid meds, pilling is out of the question.

Beasties history:
Prior barn cat, had severe respiratory problems in the late 90's. After blood work, x-rays, you name it, never found the source of the problem but keeping her in the house seemed to help tremendously and had to wonder if the barn cat was allergic to the barn (hay and straw dust, etc...) Temp never taken due to the fact that all attempts resulted in one mad cat and either the vet or myself bleeding.

Most recent:
7 June 2010 Took Beastie in to the vet, symptoms were weight loss with elevated BG (167). Amazed that I actually got a BG on her, she doesn't like being restrained. It took two techs and a vet to draw blood, when done the vet was concerned because Beastie was panting and really appeared to be struggling to breath. Vet prescribed Prednisolone for the breathing problems and said BG was ok.

Late Sept Beastie got nasal congestion and had a stuffy nose. I have Amoxicillin on hand (vet let me have a bottle of the powdered stuff due to history of herpes virus in barn kitties, I use it for URI symptoms) so put Beastie on a course of Amoxi bid for 2 weeks. Congestion cleared up shortly after starting the Amoxi as expected. About 1 week after finishing the course, congestion came back.

Started back on Amoxi and contacted vet who said that she would prefer Beastie on Doxycycline. Even though I told her that I can not pill this cat, she left pills and told me to just crush them (this was 15 Oct). Day 2 of Doxycycline, Beastie totally quit eating. I had to try crushing the pills, mix with water, and wrestle kitty to get them in her. 19 Oct, Beastie still wasn't eating at all, and force feeding is not possible. I had an appointment to take our 14 y/o Lab cross on his last vet visit and somehow remembered to talk to the vet about Beastie (different vet) and she agreed that I should put Beastie back on Amoxicillin. Put her back on it that night and she resumed eating (though still not eating enough). She had days when she was looking better, then she would look bad again.

Nov 2 I started seeing a bit of blood in the snot coming out of her nose which got worse over the next few days (I thought perhaps because she was sneezing a lot).
Nov 3rd, looking a bit dehydrated (pulled on her scruff, I am not sticking fingers in this cats mouth). Got out a LR bag and talked myself into trying to give her fluids. Amazingly enough, she was a sweetheart and let me put in 100ml.
Nov 4th woke up to a cat with a long string of bloody stuff going from her nose to her whiskers, a string about 2" long. Made an appointment for the next day and in the meantime discontinued the Amoxi. (She has not had her pred since she got sick).
14 hours after her last Amoxi, the nasal discharge was a lot clearer, some yellowish coloring but no longer bloody. Is she possibly allergic to Amoxi? Discussed this with the vet today (who was the first vet to sucessfully get her temp - he said not bad considering that she has an infection).
I told the vet that if he was going to put her on antibiotics, please give me injectable or liquid, no pills. He replied 'we are going to give her a shot of...' I thought he said Ceflaxin? He gave her the shot and said that she needs to come in for another shot in a week. This struck me as strange, and I sat in my vehicle in their parking lot for about 1/2 hour watching Beastie. I figured that if she was going to have a reaction, I would rather be there than on my way home. She looks fine so I came home and had to leave again for a bit. Came home tonight and looked at the receipt to find what he gave her and look for info on the med. The receipt says that he gave her Convenia, and the info on their site says that it's for skin infections. Is it also good for URIs? All of the info posted here on FDMB is making me nervous! And he wants to give her another shot in a week. Yes or No?
Could the elevated BG in late May have been signaling the start of this infection? How long after it's cleared up should I wait to see if she will let me test her again? Should I resume the Pred when she is feeling better?
Any thoughts on any of this? I am sorry it's so long...
 
Re: Convenia for nasal congestion?

Covenia is not necessarily a popular choice around here. Even Dr. Lisa our resident onboard vet has many concerns about it. http://www.felinediabetes.com/phorum5/r ... ?8,1905168

There are more recent posts on this board too about it. just search for Dr. Lisa or Covenia and you will find it.

Let me tell you my recent experience with covenia and this may help put your mind at ease. I have a feral that shelters on my porch. I discovered her very sick eye and nose discharge and she stopped eating. I got her into a carrier and took her to the vet. As I cannot touch this cat under normal circumstances and she doesn't want to live inside, the only antibiotic option I had was covenia - as there was no way I could medicate her and no guarantee that if I put something in the food, that someone else wouldn't eat it.

She got the shot and within a few days, I saw improvement - her nose and eyes stopped running and she started eating on her own. As this drug lasts about 2 weeks in the system, I kept a cautious watch on her in case anything happened. At the end of week one, she felt so good that she wouldn't allow me to touch her anymore.

It's now been a month and she's fine.

So, while covenia is not intended for this, under the circumstances it was the only viable option. Would I ever use this on my cats - no I wouldn't. I do believe there are situations where this is the only option and if it's used with caution and knowledge. well, it's better than the animal getting worse.

What I don't like reading in your story, is that the vet administered it, without consulting you first. I won't allow vets to do anything to my animals unless I am consulted before it's done.

I hope this helps you with your situation.
 
Re: Convenia for nasal congestion?

I agree that convenia has its place. The issue is that if your cat has a reaction, you can't do anything about it because of its long lasting nature. If you know the risks and have tried all other options, quality of life decisions can trump possible side effects.
 
Re: Convenia for nasal congestion?

I did read through the Convenia discussions here, which is why I felt that you guys were the people to ask about this... the info from Dr Lisa was what sounded the alarm for me. The discussions seemed to be pointing to Clavamox and other meds being safer, but after 2 weeks on Amoxi the only real change that I saw was the bloody discharge that stopped about 14 hours after the last Amoxi that I gave her. That led to searching for Amoxi allergy info, the closest that I saw was swelling of the throat and nasal passages. But with the possibility that she has an allergy, that would rule out penicillin drugs, I think. And Clavamox would be out, too. The Doxycycline didn't do anything but kill her appetite the rest of the way, and I don't know what other choices were available (which I certainly would have asked about if I had know the info posted here before he gave her the shot). There is no way that I can give her pills, and with the on and off eating she has been doing there is no guarantee that she will eat at any given moment even without meds mixed in her food. Perhaps he didn't tell me of the side effects because we were running out of choices? Still, it would have been nice if he gave me the chance to know beforehand (or maybe he didn't know all of the info here either?)

The thing is, he wants to give her a second injection next week. I am on the fence about this. But what ever she has is nasty and persistant, maybe the second shot is to counter the bacterial resistance as the drug wears off? If that is the case, maybe I should go ahead with the second shot to keep this from being more of a super bug than it is trying to be. I am just undecided on what to do here.

Now we are 22 hours post shot, she is still stuffy. Home treatment is fluids (got another 100ml in last night but it seems to have only lasted 12 hours this time, last time was 24+) and saline contact solution dripped into her nose to help break the stuff up.
 
We are now at 3.5 days post shot... shouldn't I see some improvement? She is no better, and it looks like the nasal discharge may be getting bloody again. Does anyone have *any* idea of what this could be? Fungal? Tumor? After 2 weeks on Amoxi, this Convenia, a few days on Doxycycline... I am really starting to wonder if it really is bacterial. I am begging for thoughts/advice! Any questions that I should ask at her Friday appointment? Anything?
 
I'd be thinking the same way you are right now - it probably is not bacterial, not after all this. Before any more treatment, I would ask the vet to please take a sample of the discharge and culture it, run some tests, swab her nose, etc. Even a head XRay if these don't show anything. I would definitely not use the Convenia a second time with such poor results the first time.

Ask your vet to call a vet school, etc., to see if there are any feline ENT specialists he can consult with.

And good luck!
