Ok Rastus Gem & I just got back from his Vet checkup & boosters.. I talk to my Vet about the FELV/FIV Testing.. She [my vet] said that yes Rastus Gem has had one set of test & all negative && he will get another set at 4 months of age.. Both viruses can rest dormant in tissue & bone merrow (spelling?) & other locations.. She [my vet] says since Rastus Gem was so clean & in good health when dumped & found & is in a indoor clean enviroment that I should not worry & that Rastus Gem should be ok..
