The selected treatment, when administered, acts as a potent emetic, especially in cats. Xylazine, an alpha-2 adrenergic agonist, is known for its sedative and analgesic effects but is also widely used within veterinary practice specifically for its ability to induce vomiting. When given intravenously, it can facilitate rapid onset of the emetic effect, leading to vomiting in a relatively short timeframe. This makes it a suitable choice in situations where quick emesis is needed, such as during cases of toxin ingestion.

In contrast, the other options do not serve as emetics or are less effective in inducing vomiting. Fomepizole is primarily used as an antidote for ethylene glycol toxicity, and while it plays an important role in specific poisoning scenarios, it does not induce vomiting. Clofazimine, an antimycobacterial agent, is not used for inducing vomiting either. Yohimbine is an antagonist of xylazine but is not itself emetic. Each of these alternative treatments has its own purpose in veterinary medicine, but none are indicated for the rapid induction of vomiting like xylazine is in felines.
