snap off the tip.

ferrets less than 6 months old.
Do not use on sick (e.g. systemic diseases, fever) or convalescent animals.

absence of studies, the use of the product is not recommended in non-target species.
Do not use in known cases of hypersensitivity to the active substance or to any of the
excipients.
Cats:
Among the very rare suspected adverse reactions, transient skin reactions on the
application site (scaling, local hair loss, itching, redness) and general itching or hair
loss have been reported after use. Excessive salivation, reversible nervous signs
(increased sensitivity to stimulation, depression, other nervous signs) or vomiting
have also been observed after use.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).
If licking occurs, a brief period of excessive salivation may be observed due mainly to
the nature of the carrier .
When treating infestations of parasites, all in-contact animals should be treated with
an appropriate product at the same time.
Special precautions for use in animals
It is important to make sure that the product is applied to an area where the animal
cannot lick it off and to make sure that animals do not lick each other following
treatment.
No data on the effect of bathing/shampooing on the efficacy of the product in cats
and ferrets are available. However, based on information available for dogs
shampooed as from 2 days after application of the product, it is not recommended to
bath animals within 2 days after application of the product.
There may be an attachment of single ticks. For this reason a transmission of
infectious diseases cannot be completely excluded if conditions are unfavourable.
Fleas from pets often infest the animal's basket, bedding and regular resting areas
such as carpets and soft furnishings which should be treated, in case of massive
infestation and at the beginning of the control measures, with a suitable insecticide
and vacuumed regularly.
The potential toxicity of the product for kittens of less than 8 weeks of age in contact
with a treated queen is not documented. Special care should be taken in this case.
Animals should be weighed accurately prior to treatment.
