Yes you can. But it takes 1-2 weeks for a venus fly trap to digest it's food. If you feed it to much it could do it harm. Also do not feed it any human food as this kills the plant. Only feed your venus fly trap insects and some grubs, if you do do so, then only feed it 2-3 times a month. you don't even have to feed it anything, and just grow it as any other plant.
