I’m glad you’re feeling relieved. The comments made were not condescending or snarky in the slightest, they were totally fact based.
This forum is great for supporting people when their emotions are heightened, but sometimes clear facts are required to help calm someones mind, and it worked because you went away and did your own research for clarity, and ultimately felt relieved off the back of it.
It’s clear you love your own cats, and it’s clear you’re watching out for the welfare of the cats in your care too, and that’s a beautiful thing to see.
