Yes, I know it is still July and very warm outside, BUT it will not be long until cooler weather is on the horizon. Each year I hope to be better organized before the cold weather arrives. I discovered last year that Amazon has open box or used heated cat pads for just over $22. They are the soft pads are measure about 14x18. I bought 2 last spring and they both work just fine. Here is a link. If you scroll down the page you will see a section that says "Save Big on Open Box or Preowned". It is there you will find the heat pad for $22.82. If you have Amazon prime, the shipping is free!! http://smile.amazon.com/Manufacturing-Lectro-Soft-Outdoor-14-Inch-18-Inch/dp/B000ICGJZK/ref=sr_1_2?ie=UTF8&qid=1438201300&sr=8-2&keywords=outdoor+heated+cat+pads
I also found a gallon heated water bowl from Walmart. Last year I bought the quart size for $10 and this year they have the gallon for $14.97
It is also Back to School time and rubbermaid and sterlite storage containers will be on sale. You can start to build your feral houses now to have them ready for cooler weather.
Just a heads up for some specials going on right now! I know the open box items from Amazon are limited quantities so get them now while you still can. Once cooler weather arrives, the price will jump to over $40.
