  1. Really well put together presentation Mel, I loved it! It was a kind of different and out there topic, but you managed to do it quite nicely. Also, you can never go wrong with cats. One question I have is, did this project impact your own cats and did you change their diet around your findings?

    1. Thanks! I really appreciate your comment!
      Your question is quite similar to Grace’s, so, in short, I haven’t changed my cat’s diet because I haven’t found any reason to belive it isn’t good for her. Of course, next year when I conduct my experiment, I can make a more hard-proof statement on the extent of effects.

  2. This was such an engaging (and aesthetically pleasing) presentation, Mel! The pH of cats in relation to cat food is definitely a very unique and interesting topic. I loved that you explained everything so clearly, and now I have a much better understanding of testing pH! There isn’t really much I would change about your presentation, but if I had to give some constructive criticism, I would suggest maybe considering adding a few key bullet points to some of your slides so that it is easier for the audience to follow along. After watching the presentation, I’m wondering how this new knowledge of the different pH levels in cat food will affect your future purchases for your furry friend!

    1. Thank you so much!
      At the moment, I don’t have any reason to believe my cat’s current food is in anyway detrimental to her health. It takes a little while to find a food that your cat likes (cat’s can be quite picky when it comes to food). Of course, when I conduct my experiment next year, I will get a better understanding of how this cat food is impacting her health, and take the next steps acorrdingly.

  3. Hi Mel! This was a really interesting topic, especially since you went out of your way to do your own testing for the project! Very cool! Despite owning several animals, I’ve never really considered the important of a healthy pH level and how their food could impact those levels in sometimes detrimental ways. I just have to ask, how exactly did you use blueberries to test pH. In addition to this, how much time does it take to test?

    1. Thank you! It took me about 30 minutes to test the pH of the cat food. If you go to my bibliography, and click on the first link, it will lead you to a website with step by step instgructions on how to make your own pH indicator using blueberries. But, in short, you crush up a couple of blueberries (seperating the skins and insides is most effective as the skin is more concentrated in anthocyanins). Then you add some warm water and strain the liquid, which gives you a pH indicator liquid, which I used to dip strips of paper in. And there I have some pH testing strips.
