There is no dirt, writing, or tearing. There are a few page-turning wrinkles, but it's a very clean book. Please check the images. Please understand that this book is stored and inspected at a private home by an amateur, so please forgive any oversights. I also have picture books, children's books, etc., for sale. Please take a look if you like. You don't have to go to the African savanna or the Amazon jungle to observe animals. For example, the stray cats in your neighborhood. "I" make cat cards, giving names to the cats living in the town and writing down their characteristics. I sit still and observe which cats come around when, and I attach a device that emits radio waves to the cats to find out where they are. I will introduce my favorite observation method: secretly following a cat for a day. This is an introductory book to animal behavior science.
