We use these for our breeding program having chihuahuas.
We usually purchase 2 of these and put them together in order
to have a bit more space if it's a puppy that will stay in the enclosure for longer periods.  1 is sifficient if only using for very
tiny breeds and for sleep time only.  We swear by these enclosures and our customers love them also.  Thank you

PS:  service is very rapid, everything is paid online so no duty and taxes to pay at the door which is a blessing.
