I am shocked they would even test at 3 weeks old to be honest. Especially with FIV kittens can test false positive for upto a year so need testing after 12 months and even if they are positive for FeLV or FIV it is no reason to euthanase. Not sure if teh same time scale applies to FeLV but I'm sure it will.
I do know that the tests for FIV detect anibodies and not the virus - the kittens automatically get the antibodies from their mother but not necessarily the virus. So like I said tehy could test positive for a long time even though they may not have the virus. Time is usually around 6 months before they test negative but I've known cats to have false positives for 12months and even upto 2 years so if they tested positive on FIV there is every chance they may be negative. Hope someone else can help on the FeLV knowledge about time scales before testing can be accurate. Michelle, Minstrel, Buddy, & Angel Bramble
