Company claims

Here’s a detailed list of insects you can use Sentry Purrscriptions Plus Flea and Tick Squeeze On for –

How it Works

Sentry Purrscriptions Plus Flea and Tick Squeeze On is a spot on treatment. It’s not clear from the product description if it comes with an applicator.

The treatment comes in two sizes – one for cats that are less than 5 lbs and are over 12 weeks of age, and one for cats that are between 2.2 lbs and 5 lbs.

Sentry Purrscriptions Plus Flea and Tick Squeeze On has the following ingredients –

  • 55.0% Etofenprox
  • 2.20% Pyriproxyfen
  • 42.8% other ingredients

Etofenprox is a pyrethroid that is harmless to humans and is environment friendly. It acts by opening sodium channels in neuronal membranes causing paralysis and death.

Pyriproxyfen prevents larvae from developing into adults.

    Just tried Sentry PurrScriptions Plus on our two cats; Molly and Matty. They are siblings and 2-1/2 years old. I specifically followed the directions on the back of the box, and within 1 – 2 hours both became very quiet and lethargic. Molly, who is smaller and lighter, reacted first, with Matty about an hour later.

    The fur on both of them has become greasy looking and matted. Both cats flick their ears a lot. Molly also acts nauseous and has small heaves like she is going to throw up.

    We definitely will stop using this product ASAP.

    I used this product on my cat today. I wish that
    I had read this before I put it on him. My cat is 1
    year old and weighs about 7 pounds. He’s very
    active and playful. After I applied this treatment
    he is just laying at my feet doing nothing. He’s very
    lethargic. It has frightened me! I will NOT use this
    treatment on my cat again and will tell everyone I
    know that has cats to never use this flea treatment!!
