Wow I'm surprised the vet was calm. Very scary. I'm glad your kitty is okay! We only ever bring roses home because we know they're okay. Even then we usually keep them up high or our boy will knock the vase over lol

Hopefully not lilies or another toxic flower. If so take your cat to a vet immediately before it goes into kidney failure (not trying to be that person but many people don't know this can happen)
