the biggest challenge of my studying!

The biggest challenge for me about my research is even though there are tons of information in interent, sometimes they are not accurate or what they are talking about are slightly different with what i am looking for but titles are related. So I guess I need to develop discernment to determine what information I need to wrtie an accurate, trustworthy paper.

And some of them are really old like published in 1960s. So use those articles as sources is one more thing i should avoid and be careful. Because as time pass by, new researches and studyies add in history of animal communication.  

 I'm wating for the book i ordered, and it sould be here in few days. So im excited about that. :)

Roxy, the neighbor cat

Even though i have a cat allergy i pleasurely invited her to my house and we hung out for a while.

  She looked kind of bored so i showed her a cat entertainment video from youtube.

the video was filmed by one of youtubers who loves animals, (it was like a home video). Birds  

I turned this video and her ears got pointy and searched for where the sounds come from.

After she found out that it was from the TV, (i moved a chair for her, so she can see them closely) her eyes were totally focused on tv screen and even tried to snatch the birds.

Could Roxy understand birds' twittering? :)

Or can't but just listen thier twittering as we do?
