Note that whatever type you buy, if you have a cat, its potential as a toy will soon be identified - with one swipe of a curious paw they'll realise it rolls easily and if you turn your back, it'll be off the table, onto the floor and away....
I started off with one of those cheap blowers from the drugstore. I have no idea which body orifice it is intended to be used in, what fearsome malady it is intended to relieve nor what method of application must be used alhough it must surely involve a degree of wincing.
Maybe I would have been happier if mine was blue rather than beige. For me, beige is never a reassuring medical color. It is the sort of color in which things are made when they are not desirable but are in hope of being concealed or minimised and the person involved has certainly turned to the item as an instrument of last resort.
I had a boyfriend with a beige company car once and it was much the same.
In any case, my overactive imagination made me wonder if people were speculating when I got my bodily aid out in public and so before long, since everyone else seems to have the rocket blower, I succumbed to peer pressure and bought the finned one.
It seems the photographer who gave me the medical orifice blaster was right, in use, it isn't any different to the rocket and perhaps, as he claimed, it is only the gullible and image conscious who fork out the extra for the rocket blower but the fins have made it less attractive to the cat so I've got an excuse.
And I don't shudder when I get it out of the bag.
