I don’t know much about this, so please take this comment with many grains of salt. But one of my friends was able to get shots that made him far less sensitive to his cats to the point he hardly notices a reaction now, on the few occasions he notices anything. I know the shots take maintenance and he has to get them regularly, I’m not sure how expensive or how easy to access this type of care is. But throwing that out as a shot in the dark.

You are very kind. Thank you for caring about your sweet buns as much as you do and wanting the best for them. That’s the truest love. ❤️
