We are going to England for 6 months with my husbands work. We started process to take our cat as the job may go longer. At then end of the process we have to have this indoor cat treated for ticks. Our Vet says there is no safe way to treat a cat for ticks - all the products are toxic for cats. I called the office in England but they said it has to be done and they had not heard it was toxic. Has anyone else delt with this?
