Concerned for my cats RAW food

I hope this is allowed here, but I’m more or less just needing to vent for anyone who wants to listen. I feed my cats Viva Raw and have for a little while now. In recent events with the bird flu situation, I’ve grown very nervous about feeding and I’m unsure of what to do except to trust the brand.

For starters, my cat who triggered my decision to feed raw has -severe- IBS and after many attempts at changing (slowly) to many, many different brands of dry kibble, canned wet food, limited ingredient diets, even freeze dried raw, and has even gone on high levels of medication and steroids with no improvement at all, we almost resorted to putting him down. He was having multiple painful movements, multiple times a day. I hated to see him suffer and prepared myself for the worst. There was only one thing left, a nagging feeling that maybe I should try raw and if it doesn’t work, we’ll make that final, difficult decision.

After slowly switching him to raw, once he was 100% converted, almost overnight he was healed. He’s fully weened off his medications and living a very normal, happy cat life. He’s been on raw food for just over a year with no accidents. Someone we thought was just an old grump wasn’t grumpy at all — he was just in pain and miserable all the time. Now he’s a brand new cat who loves to play.

For this, I know, positively, I can’t switch him to a wet canned food, dry kibble, or freeze dried raw. I’ve been thinking about switching to another brand of raw, however, that uses high pressure processing to see if he reacts but I’m terrified to do so as it’s inconclusive exactly what all might be triggering to him. Also, this stuff is pretty far over my head, so making a conclusive decision has been more than nerve wracking. After lots of research I felt most comfortable to attempt trying Steve’s brand only to realize they do not sell it in my area. Back to square one.

Anyway, all that just to again say I’m mostly trying to vent. If anyone happens to have any advice or feedback or even just words of comfort I’m all ears and appreciate it greatly. I just want what’s best for my cat. I’m worried endlessly for him and have gone through so much to make him feel normal all for it to be shattered by bird flu. I’m exhausted, overwhelmed, and can’t shake the guilt that something bad could happen or maybe I’ll do something wrong.

Thank you guys for listening.
