  1. I miss our guinea pigs. My kids had them when they were younger. They had the greatest names Fuzzlelum and Tornado. Tornado had a swirl of hair on her head. They were so cute. I never even thought of feeding them basil.

  2. Moderation always feels like it’s the best policy when giving the little guineas fresh greens, NEVER give them rhubarb, tomato greens, potato, onions, or garlic though!! Also, a good way to see if their calcium intake is too high is if their urine leaves behind powdery white traces. In these instances, be sure to cut back on greens high in calcium or you’re at risk of giving your piggy kidney stones!

  3. Very interesting post. That is filled with all this wonderful information. I never knew that guinea pigs could get scurvy. or was able to eat basil.
