You are here:



I put some fontline on my cat three days ago, and have used this before, but two days after it was applied he has gone very jumpy, hiding etc, do you have any knowledge of this, would i know if he had an allergic reaction, he doesn't look ill or anything just jumpy, thanku

I am not a vet and don't want ot give any false diagnosis of your cats problem.

i haven't heard of this happening before and if you have used the product before it is unlikely that he is allergic to it. It may just be coincidence that this has happened.

i would recommend keeping an eye on him to see if any other symptoms show and if you to seek advice from the vet.  I wouldn't be surprised though if this is just coincidence.

best wishes kate
