corona virus

I have a 7 year old cat, Rista, who through a blood panel has tested positive for corona virus. She hasn't had any health problems from it, and the vet said a cat that's positive is pretty common. However, I just brought a 9 week old kitten, Jasper, home. From what I've read, kittens that young have weak immune systems and have a greater chance of developing FIP. Right now Jasper is isolated in a room, but how likely is it that he'll catch the corona virus from Rista? Is there any way I can minimize the risk of that? Do I have to worry?

I think what your kitty actually tested positive for was the antibodies to the virus rather than the virus itself, please verify that with your vet.  If it's just the antibodies then your kitty is no longer shedding the virus and is not contagious.

Yeah, I called the vet when they opened. Her blood panel showed high titters, which I guess means that she was at least exposed to the virus, not that she has it, which is kind of a relief. She might have it, but there's no way to tell unless she develops FIP, which she hasn't.

My kitten was tested and found to have a low reading for Corona Virus.  We got her tested after she had gotten sick twice within a month and a half with high fevers, the first time throwing up big time and the second time shivering like she was freezing.  After we got the diagnosis we changed her diet to Blue Buffalo dry food with wet food once a day of either Blue, Wellness Core, Organix and things along these lines.  None of the friskies, meow mix, purina, etc.  After 2 days of being on Blue she did a complete turnaround.  She is also getting 2 Lysine medicated chews every day (1 for every 5 lbs) and she gets one in the morning and one in the evening so it stays in her system all day.  She has not gotten sick since nor has she had any signs of anything.  We also have her sister, who the vet says was probably exposed to the virus as well, but she is doing outstanding and has had no problems/issues, etc.  You can do a lot to help just by adjusting the cats diet and making sure they are eating good, healthy ingredients (we use all grain free) and nothing with by-products, fillers, etc.  The diet has done wonders and clean the litter box when they poop as soon as you possibly can.  The poop can hold whatever for several days so you want to get it up as soon as you are able.  Four months now with no illnesses.
