Pacific Chorus Frog

[lnaminneci]

I found a Pacific Chorus Frog in a potted plant on my top floor (3rd floor) balcony. I let him go in a grassy area outside, now 2 weeks later I find another one in my potted plants (either the same one or another one?) Not sure if male or female, seems friendly and happy in my iceplants. Looks healthy. He also changes color from brownish tan to green. What should I do? Let him hang out in my plants, have as a pet? (my son 4 likes him)

I will try to post some pictures I took today.
Thank you for any comments.
