Oh may. The nightmare for a rescuer...
I tried now to read a little about these in Swedish, on Agria, a major swedish insurance company for small animals. I presume it it the same sickedness.
The reading gives me some hope.
1. They say it is not so very contagious. Usually by bites, or kittens in moms womb. They didnt said during nursing or stimulating.
I know stimulating means also eating up the poo - THIS is worrying me. But they didnt said anything about poo.
2. Even if Keller gets the viruses in and tests positive, it is not at all sure the sickedness will broke out. It is not so dangerous for healthy cats, who can live long life with it they say. The sickedness may break out if their defensive system gets weakened. For example by stress, starvation or another sickedness.
I know this is correct for FIV.
So. We cant say hurrah. But I think and hope there is place for some optimism.
Lets hope the test are negative.
