16 hours after applying one dose of Sentry Purrscriptions, according to the manufacturer\\\\s directions, to my 11 lb. 1 1/2 year old cat she began trembling, seizing, pupils were dilated, she was biting multiple clumps of fur out, lethargic eye movement, vomiting and diarrhea. After speaking with my vet I was advised to bring her in immediately. They proceeded to give her a chemical bath to remove the product, Valium to calm the tremors and antibiotics. In addition to the shots, she also has a regimen of both diazepam and antibiotics she must now take at home for the next ten days. Not only did the vet say it was good I got her there when I did, but he also wrote a letter stating that the reactions my cat was having were a direct result of the applied product. I plan to pursue reimbursement for all incurred charges, as well as pain and suffering compensation from the Sentry corporation.
