Fanta (my cat) has:
a yeast infection (in both ears), which means that at some point in her young life, she had (had being the operative word) ear mites.
tapeworms (which come with the possibility of us having a flea infestation... But the vet could not find a single flea on her. We still vacuumed and sprayed.)
and a reoccurring upper respiratory infection.
When the vet tried to give Fanta the deworming pill, I absolutely panicked. I freaked the vets out so much they had to take the whole adventure into the back and leave me up front in the room. I couldn't help it, she was so pissed off and scared that she was pooping and foaming at the mouth...
And when I heard "chronic" and "respiratory" in the same sentence, it reminded me too much of my first kitten, who died the week after his first birthday (following his fifth or sixth episode of pneumonia)... I ended up lying on the floor, crying... And Fanta was hiding under the couch, making sure to keep just out of my reach so I couldn't even TOUCH her.
