Effects of an insecticidal dip containing d-limonene in the cat.
A study was undertaken to determine the effects of a single dermal application of a commercial insecticidal dip containing 78.2% d-limonene in cats. At the manufacturer's recommended concentration of 1.5 oz/gal of water, no clinical signs or lesions of toxicosis were seen. At 5 times the recommended concentration, clinical signs were mild and consisted of hypersalivation of short duration, ataxia, and muscle tremors resembling shivering. At 15 times the recommended concentration, clinical signs included hypersalivation lasting 15 to 30 minutes, moderate-to-severe ataxia lasting 1 to 5 hours, muscle tremors resembling shivering lasting 1 to 4 hours, and severe hypothermia beginning soon after treatment and lasting 5 hours. Gross lesions were confined to excoriation of the scrotal and perineal areas of the treated male cats at the 15 X concentration. No deaths or other lasting effects were seen at any dosage.
