Updated On September 23rd, 2025

Pet's info: Cat | Bombay | Female | spayed | 1 year old | 6 lbs

I tried Sentry on my cat 4 days ago, disinfected my home and my cat now is scratching more than ever. Can I give my cat a different product to use now?

He may be allergic to fleas or the product itself. I would recommend an immediate check up to determine that and have a prescription product against fleas prescribed. Comfortis could be a valid option.
