I love this cat house. We’ve had it for a couple months now and it’s still holding up great! We have a bunch of feral kitties who don’t want to be inside but come for dinner every night. I didn’t want them to be cold this winter so I researched like crazy for houses. We already have 2 smaller heated houses but our feral kitties are all a family and sleep together so we needed bigger houses. Decided on this one for a few reasons. One was the size! It’s absolutely HUGE. This was the only one I could find that was really big and had the other exit opening on the side. I wanted to put it up against our house (to help keep out of the rain) so the extra emergency opening had to be on a side, not behind. Definitely big enough for at least 2 kitties to sleep. Even though most of the other heated houses claim they can fit 2 cats, I really don’t think they can. The other one we bought that claimed it’s big enough for multiple cats… definitely is NOT. One kitty at a time uses that one and it’s an XL house! This one is just so much bigger and was the same price! Just not as well of a known brand I think. The side exit is a pro or con depending on your particular need. It zips closed to help keep the heat inside in the winter and zips open for warmer temperatures but most kitties need an emergency exit other than the main opening. In order to have that with this house you have to leave the flap unzipped. There’s no option to leave it unzipped and keep the flap as a doorway because it zips from the top down unfortunately. You fold the doorway underneath at the bottom. I think if it worked like a flap door and zipped the correct way for that, this house would be perfect. It worked good to get my ferals used to being in an enclosed space since the doorway is so wide open though. They’re pretty skittish and they explored this one immediately because of that wide open door. We have another “bigger” house that has 2 small doorways and that one took awhile for them to explore …so the big doorway definitely helped with that part. They still use this one all the time even though it may get a little chilly being so open. It’s definitely big enough for them to scoot far enough back to keep warm on the mat if it’s windy or raining. The smaller front opening does come with a clear flap to help keep the heat in. Unfortunately none of my cats have ever wanted to use the doorways with those flaps attached. I think it’s too hard for some of them to get used to going through. Thankfully it’s Velcro so you can easily take it out and put in back in as your needs require. The heated cat mat totally fits the entire inside (which is huge like I said ) and it heats up super fast and has a removable cover to wash. The structure of the house feels sturdy (the cats like to sit on top of it too ) and the insulation inside feels thick and durable. The zippers all seem sturdy and seem like they will hold up to Oregon winters. The main door has the edging around it to help with keeping rain out but idk if it really does anything like the awning type doors do? Some people said they had trouble getting the house part to fit on the assembled bars. Most houses are like that and you just have to pull and adjust. It needs to fit tight to work. In the beginning I wasn’t sure about this one because of the side door issue but our kitties totally love it and use it constantly! Definitely a win for us.
