My second density cat can see and touch me.

I remember Ra saying that those of 4th - 7th density chose of there own free will to be invisible to 3rd density.

Edit* Here is the quote.

12.17 Questioner: Does an individual in the fourth density normally appear— or, is… are they normally invisible to us?

Ra: I am Ra. The use of the word “normal” is one which befuddles the meaning of the question. Let us rephrase for clarity. The fourth density is, by choice, not visible to third density. It is possible for fourth density to be visible. However, it is not the choice of the fourth-density entity to be visible due to the necessity for concentration upon a rather difficult vibrational complex which is the third density you experience.

I hope this helps in answering your question.
