We all know how difficult it can be to make a cat vomit when we actually need for them to vomit. Veterinary emergency hospitals are encouraged to stock formulations of apomorphine for inducing emesis in dogs, but sadly this medication doesn't seem to work in cats. The theorized reason behind the feline's lack of robust emetic response to apomorphine stems from anatomical differences in their chemoreceptor trigger zone receptors where they are believed to favor more of the alpha-2 receptors over the dopamine receptor abundance that dogs exhibit. For this reason, most hospitals carry xylazine, an alpha-2 adrenergic agonist more commonly used in large animal anesthesia. However, if you've ever tried to make a cat vomit using xylazine, their response is variable and many will not vomit when appropriate doses are used. Clinically, I've always felt like it only works half the time in my poisoned cat patients!
