I might dose a 14 lb cat with 150 mg of gabapentin. 600 mg would represent a 4X overdose. Sedation and ataxia ("drunken sailor") are the most likely adverse effects to arise. In the ASPCA Poison Control Center database of 103 exposed cats, 47 became symptomatic. The most common signs were lethargy/sedation and ataxia. Treatment is basically supportive with general decontamination procedures including emesis, activated charcoal, and cathartics. To answer you directly, the vet would induce emesis by injecting your cat with an emetic drug and then dosing orally with activated charcoal. This would be prudent to have done although I don't expect your cat to be at serious risk.
