Would like to know what Cage or Crate everybody uses when traveling. Like to a family's house or friends house or even if you travel and stay in a hotel or motel. What do you have that you think is the most comfortable and easiest to use for your furbaby? Would also like to see pictures of the crate or cage you use. Could you also tell me what size it is. I don't have a Yorkie yet but want to go shopping and check them out so when the time comes I will be better informed to buy the right one. Would like to have a 4lb.to 5lb. Yorkie. Thanks..........
