I buy from my vet - he's as cheap as the mail order places (~$28 for
three cat doses).  The thing is I need 11 * 0.5 ml doses a month for
the cats and another 5.something for the dogs - say 11-12 ml a month.
individual cat doses are over $9 per cat per month, but the large dog
size is 12 ml for $36 + tax - a bit over $1.50 per cat and $3.75 per
dog per month.  I use a nearly worn out 3 ml syringe to meter the
doses (I have several spares).

I compared the ingredients and found that the only difference is that
there is slightly less of the juvenile hormone in the dog formula -
the adult flea killer is the same concentration.  Somebody in alt.cats
suggested I look into that approach, and I checked with my vet and he
OKed it.  So far the only problem has been that some of the cats don't
want me putting wet stuff on the back of their heads and struggle
almost as much as when I try to clip their claws (same cats object to
both; the others don't object to either).

T.E.D. (tdavis@gearbox.maem.umr.edu - e-mail must contain "T.E.D." or my .sig in the body)

You can buy one large dog size Advantage for the same price as that for a
cat. It's the same concentration. Draw it out with a syringe, throw out
the needle and dispense. I find that's enough for 8-10 cats.

Advantage comes in two sizes for cats
9 lbs or LESS 0.4 CC
10 lbs & Up 0.8 CC
One tube of large dog Advantage contains 4CC.

I think .4cc is too much for a small kitten. I prefer to weigh them and
use .05cc/lb. which is slightly more than the minimum dosage.
