I typed a detailed reply & was unable to post it so I will keep this short. We has used these for a number of years & love them. Don’t put one in the front seat. If you have concerns, go to centerforpetsafety.org to the main menu. Click on CPS Certified then Sleepypod Carriers. It will have a list that have passed testing. Good luck. If you have any info that they are unsafe please send me a private message. Tsk |
