I am fostering 2 kittens that I bottle fed for the first 6-8 wks of their life while dropping a children's formula nose drop in their noses to try to allow them some breathing relief. They had an URI at birth and I have treated the URI with everything from AmoxiDrops, Clavamox, Baytril, Clindamyacin, and others and they still (they are now 5 mos old) have green thick discharge from the nose and 2-3x a week their eyes are runny with clear liquid. Is this possibly a sinus infection brought on by an allergic reaction to something in my home or a long lasting infection? What else can I try to treat this with? The humane society doesn't have the funds (nor do I) to have alot of tests run on these little ones.
If the kittens have feline leukemia, feline aids or panleukopenia, the kittens will not do well. Tests need to be run to determine if they have these viruses. I would continue with clavamox drops 2 x daily and eye antibiotic ointment 3-4 x daily. If you have a nebulizer, it may help. Viruses take a long time to clear up and since the kittens have weak immune systems you are fighting an uphill battle. Good luck, vetcare
PS make sure the kittens continue to eat several times daily!!!!
