Program Suspension for Cats

A once-a-month oral suspension which has the ability to control flea populations. As an insect development inhibitor, PROGRAM does not kill adult fleas, but effectively and safely controls flea populations on your pet through a mode of action which breaks the flea’s life cycle at the egg stage.

In addition to this flea treatment you may require an additional household spray to combat fleas which may not have yet hatched or dormant fleas in and around the house. Please click here to see the range of household sprays available.

Below is the product datasheet. This has been provided by the manufacturer and should always be provided with the medication.

For the prevention and lasting control of flea infestation. Program is effective against the dominant flea species Ctenocephalides felis and C. canis. Program suspension can be administered to all cats including pregnant cats and kittens taking solid food.

Dosage and administration

The minimum recommended dose rate is 30 mg/kg/month. This is achieved by giving:
Cats and kittens up to 4.5 kg—content of 1 ampoule containing 1.9 g of suspension/month
Cats over 4.5 kg—content of 1 ampoule containing 3.8 g of suspension/month.
To be fully effective the suspension must be administered together with food.
Shake the ampoule prior to opening.
The suspension should be added into approximately half of the food ration. The rest of the food should be presented when all the dose has been eaten. If several cats are treated, ensure that each cat is fed individually. The product can also be administered by squeezing the suspension directly from the ampoule onto the back of the cat's tongue after feeding.
To open the ampoule first hold the base tab (which has writing on it) and flick the pack. Then twist off the top portion and squeeze the ampoule several times to administer the suspension.
To prevent flea infestations Program should be administered at monthly intervals for at least six months during the flea season, starting two months before fleas become active.
If the cat is already infested with fleas, no viable flea eggs are produced from 24 hours after the first administration. The speed of elimination of the infestation is dependent upon the number of flea larvae and pupae in the environment when treatment starts and climatic conditions.
If cats have a high level of flea infestation at the start of the treatment, it may be necessary to administer a flea adulticide during the first one to two months. In cases of severe hypersensitivity, further use of an adulticide may be needed.
It is essential that all cats and dogs (except unweaned puppies and kittens) living in a household are treated with Program to stop flea reproduction.
For dogs, use Program tablets.

Further information

Program contains lufenuron, a benzoylurea derivative.
After administering Program orally to the cat, the active ingredient is quickly absorbed. Sufficient absorption is only achieved if administered on a full stomach. The low excretion rate assures an effective concentration of the active ingredient in the blood for one month.
Fleas take up the active ingredient through the blood and transfer it to their eggs. The formation of larval chitin structures, a process typical to insects, is blocked and the development of their numerous offspring is stopped. A new infestation of the home with fleas is prevented.
Fleas picked up by the cat outside the home environment are prevented from causing a new infestation of the home.

It’s fantastic for cats who you are not able to pick up or touch . I find it best to just put a little food in the bowl then add the capsule and mix well . It’s brilliant.

This has made fleaing so easy. Humbug doesn’t like the spot-on treatments but adding this to her food has been undetectable by her which has made my life 10 times easier knowing she’s protected.

55 Programme without pain
Verified Purchase

By on 4 July 2017

I hated the battle to place the clearly detested drops of two other products on the cat's neck. Programme, on the other hand, is eaten without any fuss or side effects. My cat no longer runs away when I tickle his neck.

Below are some recent questions we've received regarding Program Suspension For Cats, including answers from our team.

Program for smaller cats

Ann Heaps

I have a feral cat that I cannot get closer to than three feet. There's no way I could apply spot on flea treatments or a collar. Do you still have Program for medium cats, please?

  • VioVet Staff

Unfortunately Program suspension is being discontinued so is no longer produced. There are also no suitable exact alternatives to the product. Your best option is either a collar such as Seresto which will last 7 to 8 months, or long term spot ons such as Bravecto which last 3 months at a time.
You can use flea tablets such as Capstar but these will only treat fleas, they do not last longer than a few days and so won't prevent the problem.

Flea treatment


Should I let the treated cats roam freely in the house to let any fleas that are in the house bite them so that their offspring are also dealt with

  • VioVet Staff

When treating your cat for fleas it's important you let them continue their normal day to day lives. If any fleas are present then they will be in areas that your cat sleeps or sits frequently, so yes I would let them roam wherever they can normally. Program does not kill fleas but it prevents their larvae turning into adults as it contains an insect growth regulator. This effectively prevents infestations.

Using Frontline Plus with Program


Will it be okay to use Frontline Plus in conjunction with Program to kill the adult fleas?

  • VioVet Staff

These are safe to use together, however you will be double dosing with an insect growth regulator. Program contains Lufneron which is an insect growth regulator, Frontline Plus contains Fipronil which kills fleas but also S-methoprene which is an insect growth regulator.
I would advise using Program alongside normal Frontline which only contains Fipronil. Alternatively you could switch to only Frontline Plus.

What size is large/small?


It comes in large or small sizes but what is the range for each size?

  • VioVet Staff

Hi Rebecca,

Thank you for your question.

The 133mg is for under 4.5kg and the 266mg for over.

Hope that helps,

Use Program suspension with Effipro spot on

Raymond Mayes

  • VioVet customer since 2012
  • From: Northumberland, United Kingdom

Can you use Program suspension at the same time as Effipro spot on; to disrupt the flea life cycle and also have some instant knock down of adult fleas?

  • VioVet Staff

It would be safe to give the two together since they are different classes of drugs. However it would not help that much to use the Program as well as Effipro. Program works by the adult fleas ingesting the active ingredient (Lufenuron) in the cats blood which is then transferred to their growing eggs stopping them from becoming adults. Effipro (Fipronil) will kill all fleas within 24-48hrs so the adults are likely to be dead before many affected eggs are layed. Usually you don't need to use more than one treatment on your pet at once but it is important to treat your pets environment (bedding, carpets, sofas etc) with a spray such as Indorex since many fleas live in the environment and will jump back onto your pet.

Flavour of suspension


Our cat is mainly feral but comes in the house. I've had to give up drops behind the head treatments as she's too quick at noticing when it touches and runs out. She's a spitfire to pick up, scratches and bites prove it when I get close enough to try!

She is also a small eater and can be quite picky. Above also means I won't be able to squirt it into her mouth.

Questions are -
Is the treatment flavourless or does it have a cat enjoyable flavour which might temp her to eat her food with it in anyway?

  • VioVet Staff

The flavour and odour of this product seem pretty neutral to cats. A hungry cat will eat food with it in quite happily. A fussy or nervous cat will be able to tell that the food is not "normal" and will not be inclined to eat it. The best way round this is to offer it at a time when the cat is particularly hungry (miss the previous meal perhaps) and then add it to a new food which has not been offered before. Ideally this should be something the cat really enjoys, though this is difficult to predict when you have never tried it before! You could try some mashed up prawns, liver pate, tuna in oil, stir-fried chicken wings or whatever. Cats as you describe are never easy. I would however suggest not giving too much food at one time - over-feeding (relative to their appetite, not what you think is a portion) is always the way to produce a fussy cat. A regularly truly hungry cat is never fussy.
