I feel that this test is very helpful in ruling out feline leukemia when a cat is sick. The test is not expensive. It only costs about $20 and is worth not having to worry. My cat just had this test done yesterday, because he had been throwing up a lot and was not eating. It came out negative, but the $20 was worth knowing what exactly was making him sick. It turns out that he has pesticide poisoning from a flea treatment and may not survive. I have a thread telling Squirt's story and some info. on the product I used that poisoned him. You should check it out under "cat health".

Hope I could help in your decision!
