Aggressive cat at the clinic: gabapentin before the visit
8-year-old healthy cat that hissed, bit and needed sedation to be examined at its last visits. It must come back for a check-up and blood tests.
What is the most appropriate recommendation?
chevron_right Show answer and explanation
A. Oral diazepam at home before the visit
Oral diazepam in cats has been associated with idiosyncratic acute hepatic necrosis, sometimes fatal. It is not recommended for this use.
B. Oral acepromazine at home before the visit
Acepromazine sedates but does not reduce fear: the cat may be less mobile but just as frightened, and the defensive reaction persists.
C. Oral gabapentin at home, 1.5–3 hours before leaving, together with gentle handling (familiar carrier, towel, no scruffing)
Correct. A single dose of gabapentin before the visit reduces fear and aggression and makes examination easier, with few adverse effects (transient sedation and ataxia). In cats with kidney disease the dose is reduced.
D. No medication: firmly scruffing it is safer than medicating
Scruffing increases fear and stress, makes subsequent visits worse and is discouraged by cat-friendly handling guidelines.
lightbulb Key takeaway
Ask when booking whether the cat has been aggressive before and prescribe gabapentin for the next visit. If a very aggressive, unpremedicated cat arrives as an emergency, sedate it in its carrier or with a towel (opioid with alfaxalone or, if stable, with dexmedetomidine) instead of struggling.
