My crassula springtime plant is developing scarrish looking brown spots on the leaves and tips of a few leaves. I have done numerous searches on the internet, but found nothing that mentions crassula springtime. Should I be worried about the spots?

Note: I just recently brought the plant indoors and have it in a window with plenty of light. I have two cats that love the plant, but they only rub on it and never eat the leaves. No signs of any other problems except for the spots. Also, my jade plant has a few brown spots which I've read is from water splashing on the leaves and then the sun scorches it. Could my springtime have the same issue?
