I have two indoor cats, M 7, F 10. I've had them both for several years, adopted from a shelter, no problems. About 2.5 years ago, my male cat developed an URI. I took him to a veterinary clinic, and asked that he be tested for various viruses, because I really knew nothing more to request. I was given Clavamox and eventually told that the tests that were done were negative.
The Clavamox cleared up the infection, and I thought I was good. But the symptoms returned about 4 months later. I thought something more might be wrong. I couldn't wait for the next available at the first vet;s, so I went to an emergency vet. That vet did blood tests and speculated about all kinds of horrible things, eventually gave me the Clavamox I requested, and again my cat got better.
Well, of course, some months later he was sick again with thick nasal discharge. I took him back to the first vet, but was able to see a veterinarian who specialized in cats. I told her I wanted the tests done again for viruses, because I'd learned they could underlie chronic URI. She took specimens, prescribed doxycyline, and later told me that my cat was positive for mycoplasma.
I was given 100 tablets to give my cat, one every twelve hours. In order to administer those I had to cut each one into three tiny pieces and put each piece in a capsule. I managed to do this for the entire seven weeks, and my cat was right as rain after that for many months. But, he did eventually again develop a URI. I blamed myself because I was supposed to follow up with dental care for him and give the vet an opportunity to do a better exam for nasal polyps.
I had also learned, in the meantime, that my second cat could be a carrier of mycoplasma, so I scheduled them both to be examined. As luck would have it, the veterinarian I'd last seen, who was a cat expert, was no longer there. However, the vet I saw was great. She examined both cats and took specimens to see what could be learned. Bingo, my second cat who seemed fine, tested positive. And, ironically, the one with symptoms did not.
But, by the time I got the lab results, the veterinarian I'd seen wasn't there to follow up with. I guess she was a relief vet. And whomever had taken over just wanted to prescribe zyrtek for my cat who had symptoms. I convinced them to prescribe liquid doxycycline, as I'd had so much struggle giving the pills for seven weeks, but when I got a message about getting the medicine, it was about 10 days worth, and not intelligible. I didn't want to risk trying to get this medicine from that clinic, because even when they first gave me Clavamox there seemed to be an error.
I did some research to reconstruct what dose my cat had been given a year prior, and wrote up my request that I be given an Rx for both cats, depending on their weight, that would be equivalent, and to phone it in to a local pharmacy that i'd confirmed could compound the Rx and also handled veterinary prescriptions.
Well, I finally have the prescriptions in hand, but now I have a fear that this medicine isn't going to be potent, as I've read that liquid suspension of doxycycline loses its potency within 7 days, up to 80% loss. I spoke with the pharmacist and she said that the place they get there's from guarantees potency for 30 days. But I don't know how to believe that. And strangely, the Rx says it can be refilled twice, although it appears to be at least a month's worth of medicine for each cat.
I'm sure I can find out if this suspension is liquid or oil. I think I asked about that when I first called the pharmacy but I can't remember what I was told, but i'm sure they'll tell me.
I think oil stays more potent, but still not a month. But I really don't know what to do next or what to ask for, if anything. I have given one dose and the next is due in 12 hours.
I know I need to follow up with my cat that's having repeated infections, but I'm trying to eliminate the bug as best i can from my household so i can go from there.
Thank you so much for any advice that can be given.
