Small Size. Big Benefits.

Credelio Cat chewable are formulated with just the right amount of lotilaner, a powerful isoxazoline active ingredient that is extra-purified for maximum benefits.

Benefits of extra-purification:

  • Better efficacy with the same dose of drug
  • Allows for a potent, small chewable that's easy for cats to take
  • Less potential for side effects
  • Less strain on the cat's system

Lotilaner was hand-picked from over 1,000 isoxazoline compounds during development for its efficacy and safety profile.

Formulated to Pass the "SNIFF TEST"

While palatability is important, cats actually have 70% fewer tastebuds than dogs and rely heavily on their olfactory sense when determining what is desirable to eat.

Credelio Cat development:

  • Highly emphasized product smell and flavor
  • Heavily considered cats unique eating behaviors and physiology
  • Tested multiple flavor/smell attributes

Testing determined that vanilla and yeast were the power combo credelio cat needed.


There are no known contraindication for the use of Credelio Cat.


Not for human use. Keep this and all drugs out of the reach of children.

Keep Credelio Cat in a secure location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose.


Lotilaner is a member of the isoxazoline class. This class has been associated with neurologic adverse reactions including tremors, ataxia, and seizures. Neurologic adverse reactions have been reported in cats receiving isoxazoline class drugs, even in cats without a history of neurologic disorders. Use with caution in cats with a history of neurologic disorders.

The safety of Credelio Cat has not been established in breeding, pregnant and lactating cats (see Foreign Market Experience).

The effectiveness of Credelio Cat against Ixodes scapularis in kittens less than 6 months of age has not been evaluated.

Works, but use with caution
September 12, 2022
I am using this product for a couple of feral cats within my colony that cannot be handled (re: to do topical flea applications). I am so very glad that a monthly oral is even available now. I used at the dosage stated on the box (1 pill indicated for a large weight range). However, both cats experienced side affects - 1 hid/was unusually quiet for the day, the other threw up and obviously felt poorly for 36-48 hrs. The product has allowed me to get on top of a flea infestation, and the completely scabbed up neck on the latter cat is now much improved and he no longer scratches incessantly. It's time for the second dose. This time I will calculate the dose needed for efficacy based on estimated weight, and will give partial pills, then I will watch them both closely.
  • A working treatment for cats that cannot be handled. Flea infestation much improved.
  • Obvious side affects - made both cats ill for a short period. Dosage on box is more than is actually needed for cats in the low end of the stated weight range.
