A very warm welcome to you, @ana6! 
I am so happy the signs have got you started on your exciting new journey, and we are very blessed to have you with us! 
It sounds like you are right that the universe is reaching out to you- and very interesting that one of the most powerful signs was through a cat! 
If animals have an important role in your life and your practice, the topic of Familiar Spirits and Power Animals may be of interest to you! 
@Francisco has shared some great starting resources- I might also suggest browsing through the Spells8 YouTube Channel as a great overview of possible topics to look into 
.
Feel free to reach out in the forums with any questions, guidance, or experiences you would like to share. We are all learning and growing together here- you are a very welcome member of the community! 
Blessed Be!
