Veterinarians agree that Program Suspension For Cats is a good choice for internal flea control for cats, both because of its effectiveness and because it's usually easier to give medication to cats in liquid than in pill form. Program won't, however, suppress ticks or other parasites such as heartworm, hookworm, roundworm and ear mites It also won't kill adult fleas, although it can be used in combination with a medication that does, such as Capstar for Dogs and Cats (*Est. $30 for six doses). Because it is an oral medication, Program Suspension poses very little risk to humans, and side effects in cats are rare and usually minor.
Program Suspension earns good recommendations from veterinarian Eric Barchas, writing for Dogster.com, and the vets of Main Street Pet Care. The UK-based Feline Advisory Bureau also recommends this product. SimpleSteps.org, a flea-control website run by the Natural Resources Defense Council (NRDC), says that the active ingredient in Program Suspension poses a low toxicity risk to pets and humans. The Veterinary Partner website offers additional information about this product's benefits and limitations. We found only 30 or so reviews for Program Suspension at 1800PetMeds.com, but most of them are highly positive.

The website of this veterinary hospital goes into great depth about anti-flea treatments. Program products, including Program Suspension, are called the best available flea treatments for cats, but the hospital warns that they take a long time to wipe out an infestation because adult fleas are not affected.

VeterinaryPartner.com is a resource for the veterinary industry. Veterinarian Carol S. Foil looks at how the various flea control products stack up to one another. She says Program Suspension is effective in breaking the life cycle of fleas, but that it can take quite some time (4 to 7 months) for it to completely get rid of them. Because of that, using Program with another product to kill adult fleas during the first few weeks of use is recommended.

Program Suspension for Cats is not evaluated in this website's directory of flea products, which rates based on the toxicity of the chemicals used. However, the site does give a low toxicity rating to Program Flavor Tabs, which contain the same active ingredient.

The product earns an overall rating of 4.5 stars out of 5, with 4.4 stars for effectiveness and 4.5 for ease of use.
