Taxy, I hope the vet had an easy solution. Something like the feline equivalent of Tums. Or mouthwash.
When we talked to our daughter on Sunday she told us she and her brother were taking her male cat (originally called Smokey but now he is Dan - he had a bad case of dandruff), to the vet Monday. He had a stroke back in January and he's been on-and-off with improving ever since. She was afraid Dan needed to be put down.
But she didn't call last night and our son didn't post an "rip" on Facebook so I'm guessing Dan lives on.
