my cat got eaten

[Griselda]

Frontline, that flea-treatment for cats, also kills ticks. The trick is that you need to reapply it every 30 days for ticks, even though you could maybe go a bit longer if you just wanted flea control.

Frontline is pretty spendy, but it works well. Before buying any cheaper version (I see "top spot" stuff all over the place these days), I'd at least make sure it had the same active ingredient.
