Are You More Likely To Get Conjunctivitis With Kidney Disease Will A Stray Kitty Living On My Porch W/ Eye Conjunctivitis Spread It To My Dog Inside?? ?

Will a stray kitty living on my porch w/ eye conjunctivitis spread it to my dog inside?? ? - are you more likely to get conjunctivitis with kidney disease

There is a stray cat, which was presented last week at my door ... Me, a lover of animals impressive, I took upon myself to buy some cat food and fed .. then of course they are now sleeping in the chair on my porch and he is always there when I opened the door, it's alright with me, you will probably take to get neutered spayed / if I am a little more confidence. But today I noticed that one eye is half closed and not a lick .. / Yellowish transparent liquid, I'm pretty sure it's conjunctivitis, but now I am worried because my 1 years old adage Beagle use the bathroom, they can contract the disease or is it strictly a cat virus?
