Cat poop and urine can be damaging to plants and is dangerous to human health. However, as long as you remove it from the garden, it is unlikely to cause an issue. If the cats are pooping right around the base of the plant, consider putting up cages or wiring around the plants to keep them away. If the cats are going on the mulch, it will provide a good layer of protection and prevent the waste from directly getting into the soil, but you will still want to be diligent in removing any waste, as well as the mulch or soil immediately around it. Additionally, when you harvest the tomatoes, you should wash them thoroughly before consumption. Consider putting chicken wire or some other fencing around the entire garden bed to keep cats away.
