I’ll leave the rest alone, because a cat-resistant yard (i.e. your cat can’t get out - strays, wildlife, mean people, etc. can’t get in) is, as I said earlier, something I would totally do for my cats if I had a house and a yard (and the money). Though me, being a little more on the paranoid side still wouldn’t let them out unsupervised.
However, in your quote above, you again (seem to) state that being fixed has anything to do with one cat infecting another. I gave you three different sources, one of them your own, that states quite clearly that the majority of FIV infections are caused by saliva to blood transfer (i.e. biting - usually from fighting, which is why stray males are more likely to contract FIV), NOT by (cat) sperm to whatever transfer (i.e. mating).
I’m quite aware of that. I had one cat that was FIV+. I didn’t know it until Tawney was 10 years of age though and diagnosed with lympoma. I lost her brother 9 months earlier (just 1 month before she was diagnosed with cancer) before that from renal failure (he probably was FIV+ as well considering they were littermates). They were strictly indoor cats both their entire lives. They were both tested as kittens (and found negative). However, I’ve learned since finding out about Tawney that if you test under a year of age, you can get a false negative (or false positive), so I can only imagine that their mother was positive - they were never around another cat.
My point is that keeping your cats inside isn’t a guarantee of a life free from disease and early death, but letting them roam free does significantly increase their chances of said disease and early death. I love my cats (past, present, and future) enough to do what I can to give them an edge.
