THis may be a silly question but I will ask anyway. I am going to be traveling home with my cat in December. I purchased a Sherpa soft-sided travel bag so she will be comfortable during the trip. I will be medicating her for her nerves and safety. I would like to know how I can give her water (and food if she needs it) with a Sherpa bag? The watering bottles are a little hard to use. Is there some sort of trick to using them?
