Would want to rule out dermatophytosis too.

Really? do you have any papers/reports on this, as it is not my experience

Later onset of feline allergy is often more associated with food than environmental allergens ( by a long way), but these two are less likely as a new disease in older cats. Insect and other ectoparasite hypersensitivity can come at various times depending on dose and type of previous exposure.

He means Bravecto (fluralaner). Thankfully these two MSD products with such similar names don't sit near each other in practice dispensaries, however once the dog injectable comes to market it's an extra point of caution to note.

As a precaution against accidental mis-prescribing/dispensing, we have not stocked peridale (given for constipation in cats) since the packaging became visually the same as pardale (kills cats).

If there's a drug company representative watching, please don't market your drugs to all look identical on a shelf, and try to choose as distinct and different sounding names as possible.

I'd Bravecto, Depomedrone, clip claws short and see back in a couple. of weeks. Owner compliance of pills in cats is really poor in many cases.

Thanks very much for this, I will have a look at the papers (which may well answer the following question..) but is it normal for these things to come on later in life in cats?

I will look at switching to prednisolone.

Thanks again, Holly

Hi Holly

Prednisone rather than prednisolone is not well metabolised in cats so changing steroids might be useful (Rosser, 2004). Unless there is cytological evidence of infection, I suspect the antibiotic is superfluous.

Head and neck pruritus can be caused by food allergy, insect bite hypersensitivity, Neotrombicula mites, fleas and less commonly at this age feline atopic syndrome, Demodex gatoi would be possible, but the distribution fits well with IBH due to the mosquitos you describe. There does not appear to be enough crusting for pemphigus foliaceus that would be possible DD and as ever, if there is poor response biopsy may be useful.

There were some great new papers recently redefining hypersensitivity in cats as listed below. They are all open access.

Looks nasty

Any other areas affected?

Any ear or dental disease?

Ruled out fungal?

Up to date with ectoparasite control?

Whatever the cause, I guess the way forward is corticosteroids in the short term +/- biopsy if no improvement.
