If you remember, I purchased a pair of jammies for each of the boys a few months ago. I've tried a few times to get them to wear them, but they always fussed about it. With the temperatures dipping down into single digits the last few days, Hoss has been a bit whiney. I thought maybe he wanted attention since he doesn't whine about food or going potty. When I went to lay with him and rub his tummy, I noticed he felt chilly. So.........I pulled out the jammies and gave them another try. Wouldn't you know, IT WORKED!!! He is now zonked out!!!
