I accidentally left my cat's probiotic out of the fridge.

Hi all,

I took my cat to the emergency vet last night because she was vomiting and not eating. We were there for 3 hours and it was 4 AM when we got home, and I stupidly forgot to put her Visbiome probiotics in the fridge. They are in there now, but they were unrefrigerated for about 6 hours. They also did not seem cold or refrigerated when they gave them to me.

Will these probiotics still be effective or should I go get more?
