Description
General Topology"The clarity of the author's thought and the carefulness of his exposition make reading this book a pleasure," noted the Bulletin of the American Mathematical Society upon the 1955 publication of John L. Kelley's General Topology. This comprehensive treatment for beginning graduate level students immediately found a significant audience, and it remains a highly worthwhile and relevant book for students of topology and for professionals in many areas.
"The clarity of the author's thought and the carefulness of his exposition make reading this book a pleasure," noted the Bulletin of the American Mathematical Society upon the 1955 publication of John L. Kelley's General Topology. This comprehensive treatment for beginning graduate-level students immediately found a significant audience, and it remains a highly worthwhile and relevant book for students of topology and for professionals in many areas.A systematic exposition of the part of general topology that has proven useful in several branches of mathematics, this volume is especially intended as background for modern analysis. An extensive preliminary chapter presents mathematical foundations for the main text. Subsequent chapters explore topological spaces, the Moore-Smith convergence, product and quotient spaces, embedding and metrization, and compact, uniform, and function spaces. Each chapter concludes with an abundance of problems, which form integral parts of the discussion as well as reinforcements and counter examples that mark the boundaries of possible theorems. The book concludes with an extensive index that provides supplementary material on elementary set theory.

great dog toy for small and large!
Size: Medium (Pack of 1), Style: Gator
we have a very large silver lab that tears through toys, and very fast! some toys only last a day while others last a week or so... he has yet to tear this on up at all and we have had it for about 3 weeks. we also have a very small teacup yorkie, so some toys we get he cannot even play with, this one he can squeak and carry around which is great! it very quickly became one of their favorite toys! will buy again if he ever does destroy it !!!
update: after a month of the lab and small yorkie playing with this some of the fabric stared to tear on the end of the toy, they still love it and it still squeaks perfectly fine. didn't think it would last this long with the big lab, will order new one when they do finally destroy it for good

A must have for my little puppers
Size: Small (Pack of 1), Style: Monkey
Bought this for a Chihuahua. He came from a bad situation that gave him screaming dreams of terror in the middle of the night, waking up, screaming. I would find him frozen in absolute terror. Poor dude. Now, he seems full of rage, and I get it because I know half of his story. And we love him anyway. He has 2 big brothers that will help show him the way, living his best life ever!
Long story short; I first started buying this Petstages toy many years ago for my blind MinPin. Seeing it still, out here for sale always puts a smile on my face. Back then, they were a better quality. Now-a-days, the material around the squeaky is on the loose side, making it easier to destroy when my big dogs get it.
Still, it brings back wonderful memories, is soft for a small dog that doesn’t destroy his things, it squeaks and they are usually loud (which is a must have, if you ask me), and it is cute to boot!

Had big hole in it
Color: Perching Perfection, Size: 7.5" x 6.75" x 6"
This toy had a hole in it when I got it. Like they missed a seam. I meant to return it. But I had a lot going on and forgot to. My dog loved it when I showed it to him. I handed it to him then realized it had a big hole and I had to take it away. Poor guy. He really wanted it.
