At what point is it important to start interferon?
As soon as your pet tests positive to FeLV. Do not wait until your pet is in the middle of a full-blown crisis and it’s health is very bad. For interferon to be effective it needs to be started as soon as the cat tests positive. Tamlin never did get out of crisis, so he was not able to begin the interferon treatments. The vet that we had when Tamlin was first diagnosed did not believe in using interferon. I was told that it was too expensive and they wouldn’t do it. Then I did some research and found out that is wasn’t expensive. The second thing I did was to find a new vet, but by then it was too late. Do not be afraid to search for a vet that is agressive in fighting this disease.
