Also, just wanted to mention, in case I didn't make it clear. The Vet said that this did NOT seem like it was related to the FELV, but more in lines with trauma. However, I do not know enough about it to be able to come up with my own opinion about it.
When the kitten was first brought into the nursery, it was positive with FELV. a couple months ago, we retested and it was a "strong" positive. However, another thing to note, was that the Vet mentioned that it seemed more in line with a trauma. He is an indoor cat, so very little can happen...
We have a cat that is ~8 months. Male. Positive for feline leukemia. Was brought into a kitten nursery at <week and we adopted him and was bottle fed. No other known issues.
About a week ago, the cat started having a slight lethargic look and became very "lazy" as in it would just lay and sleep...
