I was convinced that my older cat (and myself) was suffering from fleas so I bought Sergeant’s Silver Flea and Tick killer in powder form and rubbed it over her body. Within minutes she starting behaving very strangely and foamed out the mouth profusely. I put her in the garage where she continued to behave very strangely and I noticed that her eyes weren’t dilating properly.
We called the helpline and got no response and it wasn’t until I found this website that I figured out that the product was extremely harmful to my cat. I washed her off in the shower and she seems to be doing better now but it breaks my heart to think I could have KILLED her if I had applied a stronger dose or she had gotten outside and I wasn’t able to bathe her.
