The feed stores sells them for $7.00 each some feed stores charges $10. The one in the Southside on Roosevelt right at the corner to your right at the red light. They sell them for $7.00. But, if you don't want to go there. Vet Clinic on PLEASANTON and S.W Military next store to Pizza Hut sells them for $21.00 each pill. But it covers fleas and tick in 1 pill. It works fast and I recommend it. The pills at the feed stores usually works by the 2nd or 3rd treatment... trust me I tried it already. It works, but after 2nd or 3rd treatment. But, if they are ferral cats. You might want to take them to the animal shelter. They give them all their shots, and I think flea treatment. I would think to control infestation within the buildings. Best of luck...
There is a program I used it for my cats but it's just for shots and to fix them not for fleas
I been believe they have a feral cat colony program. You should call to check.
