Negative for cats
I'm not sure who thought this would be acceptable for dogs and cats, but they're the size of a quarter! What cat wants to eat this medicine?
Interceptor 51-100 lbs. chewable tablets for dogs.
My dog always loved the other ones she had, they were for a lesser weight. We had to get her the 51-100 lb this time & she wouldn’t eat it at all! Not happy that I had to trick her to eat it, well swallow it because she wouldn’t chew it!
Prescription delivery
So convenient - saves on gas by eliminating trips to the vet office.
INTERESTING
It is advertised as chewable tablet, however it took my cat awhile to chew it - she first played with it awhile. She use to chew Heartgard immediately but I had to switch to Interceptor because of her weight.
Love Chewy
Chewy comes through every time. Love their auto delivery. It arrived just at the right time.
Love Chewy!
Love the fast and easy way of taking care of our pets!
Great Service
Marlin's Vet has prescribed this since he was a puppy so decided to try the purchase thru Chewy. They obtained the Vets written prescription and filled the order promptly.
great item
I find the Interceptor heartworm tablets to be very effective, and since they are chewable, my dog just "gobbles" them down for his monthly dose.
so far so good
Chewy is always reliable and ships fast. I opted out to buy from chewy than from my vet because of it. My dog had no side effects from this med. Switched to it this time as she developed hot spots after proheart-6 injection. So far so good. Seems to tolerate well.
