Thank you, everyone, for your wishes and prayers. This has been a very trying time. (I also badly hurt my leg in a serious car accident!)
My "girls" are 4 years old and are sisters from the same litter. I bred the mother, Tristan to a tom who had a good bill of health. He did stud many other kittens, all are healthy.
I obtained Tristan from a vet in Pennsylvania who gave her the first vaccinations. Tristan is well and now 10 years old.
My girls and their mom are indoor cats, and did not have contact with other cats by their own desire (snobby and terratorial). Only the breeding encounters.
I am perplexed about where FeLV possibly came from (if its true). They have been vaccinated against FeLV along with other routine shots.
The cat that who had the + FeLV elisa originally was brought to the vet for gingivitis. (This malady is common among Somalis).
Her blood work, CBC w/diff, LFTs, chem 7, albumin were all normal. She is eating, doing poops and peeps in the litter box, and is very animated.
I discussed the situation with a vet friend who said the ELISA has a 40% false positive rate. He heard a lecture from the man who created the test. My friend said I should get IFA. I will do that next week.
The mystery continues. Thanks for all your support
