Hi! I can't help regarding the dewormer, but I am sending a LOT of good thoughts
I deworm the cats regularly but I haven’t done him since he got sick. The vet brought up deworming for some reason.Hi. I hope the antibiotic helps Apollo! I realize you didn't want to put him through any more stress with the deworming, but just be careful with keeping him isolated from the other cats because if he does have worms they can be transmitted to the others. I am sure you know that already, but I just don't want to see you have any more stress than you've already got.
It is very normal to go through all of the 'what ifs'. But, none of that will change what has happened, and could possibly lead you to conclusions that you will never be able to confirm, and might ultimately regret.I'm just afraid those minutes could have saved his life.
