Hi! I adopted an FIV+ cat this past August. From reading online, I didn’t think they would get sick too much more often than FIV- cats. I decided to adopt knowing that some might be turned off by his FIV status and knowing that I am lucky to be able to afford vet bills.
BUT this is the third upper respiratory tract infection he has had in 5 months. Each time, it doesn’t seem to clear it on his own without antibiotics. I’m concerned he’ll end up with antibiotic resistance over time if I keep doing this.
The first illness, he was given both oral antibiotics and eye drops for 2 weeks. The second time (several months later) his eyes weren’t as bad and they gave me a supply of oral antibiotics only for 1 week (wish it could have been 2…didn’t realize they only gave me enough for one). It’s been a couple of months and he’s sick again. I’m gonna take him in a few days if this doesn’t start to clear again.
Some notes:
-He is an indoor only cat. I do not have other pets.
-He was swabbed for herpes one of the times and it was negative. One of the times he had a mycoplasma infection and the other time he was not swabbed.
-He was tested as FeLV- at the shelter. But I suppose if he had a very early infection, it might not have shown up.
-He mostly acts pretty normal during his infections thankfully (eating, using the bathroom, etc)…just maybe sometimes a tad less active.
-I’m going to start giving him lysine powder daily in his food (twice a day). The vet had me give it to him for the duration of the first infection, but I may as well just continue it forever since it seems fairly benign.
Thanks, guys!


Speak to your vet about possibly administering interferon. As far as I know the evidence for interferon to treat FIV is iffy at best but have had a positive experience myself.
Don’t forget that a lot of the symptoms that manifest (weepy eyes etc) are secondary and even if the interferon doesn’t help manage the FIV you might see positive effects on any secondary viral infections.
Depending on where you reside, interferon can be VERY expensive though. There might be a cheaper oral alternative but I’m only familiar with the injectable versions.
Hope this helps
