I have a problem with my sister's 3 year old cat. Whenever a plant is brought inside the house to accent the decore or other purposes (In my case, I have two young plants that will produce tropical fruits when mature); my sister's cat has a rather bad habit of eating any plant down to the soil. Right now, my plants are placed inside the aquarium for protection. Eventually, these plants will out grow the aquarium and will have to be placed out in the open with my sister's cat lurking around. For those with cats, what do you recommend for a course of action that would curtail the cat's ambition to destroy any plants inside the house? Your input is greatly appreciated.
