SureFlap - Sure Petcare Microchip Cat Flap, White, Scans Pet's ID on Entry, Check Your Cat's Size,Flap Opening is 4 3/4” (H) by 5 5/8” (W)

I’m very happy with this purchase! Both of my cats are microchipped, and the door works great with them. My female cat quickly learned to go in and out, and my male cat — whose chip is slightly shifted — figured it out too. He learned that when the door clicks, he can enter. I finally sleep through the night without interruptions, and I no longer worry if I’m away from home. The door only opens for my cats, so I don’t have to worry about unwanted visitors. Highly recommend for anyone with outdoor or partially outdoor cats!

I just installed this flap today after having problems with next door's cat coming into the house to eat. This wouldn't have been an enormous issue (he does no damage and my cat gets along with him) except that he has a long running feud with the local bully, a black cat who attacks all the other cats in the area. Last night was the final straw when they evidently were both in my kitchen yowling at one another! This freaked my cat out so I decided enough was enough and went out to get a file to make the existing hole fractionally bigger so I could install this flap which arrived a week or so ago. That was no problem, I enlarged the hole and slipped the SureFlap in place. Within a few minutes, the interloper was trying to get in, to no avail.I programmed my cat into it without any difficulty, her chip is right between her shoulder blades. But getting her to use it... there's another thing! I went outside and lured her out. It took a while but eventually she figured out that she had to push it with a paw and not just her nose. However... going back in. So far she still hasn't done it. Once outside she sniffed about then took a look at the new door. It was very sunny and the plastic is highly reflective. She saw herself in the door, thought it was a strange cat inside her house and freaked out. She puffed up to twice her normal size and shot off around the side of the house. It was very funny but obviously I had to solve that. So I got some mud and smeared it on the outside of the flap so that it wasn't as reflective as it used to be. You can still just about see out of it if you're inside, but on the outside unless the light is on indoors you can't really see through it any more. She then was happily sticking her head in the tunnel and you could hear it click quietly which makes her start just a little. I'm hopeful that she'll get used to it quickly because I can't be having the big bully coming into the house tearing her to pieces. My main concern right now is that she is used to hurtling through the door when she runs away from him. (Until last night he didn't seem to have any notion that he could come in but now he's seen the other male do it I think he figured it out.) I don't know if it will react fast enough and open the flap without her smacking into it. It may put her off of using it altogether. I'll report back on progress in a while.Jan 9, 2012A month has now gone by since my cat began using this new flap. It took her a couple of days to start using it to enter the house. I ended up having to cover the inside and outside of the flap in white Scotch tape so she couldn't see her own reflection (but you can see kinda see through it). That was freaking her out a bit so perhaps something for SureFlap to consider in future. Maybe offer an opaque door flap as an option. On the whole though this door has been a life saver. It stopped the other cats from entering - maybe he's brighter than your average kitty but the main offender learned almost immediately that he could no longer get in that way and stopped trying. The only problem, if you can call it that, is that my cat can no longer hurtle through the door, it just doesn't react that fast. But she's learned that and doesn't try to enter it at a run. I worry a little that she may get caught by the big bully cat who occasionally chases her but so far that hasn't been the case. My only other concern and perhaps someone can inform me - does it give you any warning when the batteries are about to die or do I need to test them periodically to see how long they're likely to last?March 10, 2012There's a slight flaw in this door but I guess not likely to affect most users. My cat is constantly being chased by her enemy, the female cat who lives next door. One day recently she was in hot pursuit and when Mizz came through the door she was so close behind that she was simply able to follow her in because the door hadn't yet shut. This can't be called a design flaw, it's more to do with the nasty character of the cat next door but if you're thinking that it's completely fool proof, it's not. As luck would have it, my husband and I were both in the kitchen when this happened so no fight ensued. The interloper was terrified to find herself in this strange situation and being unfamiliar with cat doors she didn't simply turn around and go back out, instead running off into the house. Hopefully the experience scared her sufficiently that she won't do it again! Regarding the batteries, I tested them and three months after installation they're still almost at max strength so they're going to last a long time.Overall I highly recommend this product; it's miles better than the ones that rely on a collar tag, the microchip isn't going to get lost!

These doors have been a life savor!We have multiple cats that eat different food or like to guard their food.Was able to create separate feeding enclosures using these doors allowing them their own spaces.

Great little unit! (slaps top) this thing will fit your mid sized tabby or orange boi with lil to no issues! Your furred ones will be able to sneak in and out at their leisure all while this door eliminates you of any door duties . My cat is was a bit hesitant and he has a litter loo and loves to come and go, but once he got the "swing" of this door he was happier than pigs in the pen!! Lock works good, and I trust the RFID and speed of door will keep unwanted critters from partying like andrew wk in my garage!Missed a 5 star due to one thing I see they could improve and provide to their customers. That is a longer tube/tube extension for a little wider wall, or door. Its not a huge deal, and its not like most people will need more than whats supplied....but the option to be there would be SWEET!Sureflap is awesome and if they keep it up I can see them on alot of doors in peoples homes and businesses

The media could not be loaded. I installed the door and got it working using a collar microchip. It took a while to get my cat trained to it but eventually he figured it out. I was manually closing the cat door for maybe 5 months prior to installing this and spent loads of time after training and checking that the door was functioning properly.Finally satisfied that it was functioning well and my cat was accustomed(at least 2.5 weeks) i allowed the door to run autonomous only to lose my cat within 3 days of this decision.The raccoons or opossums that were invading the garage this was installed on meddled with it enough to get in from the outside by pulling out on the door from underneath. The critical flaw with this design is the draft stopper material that became dislodged with this effort and became wedged in the opening so the door was not able to be pushed open, trapping my cat outside for several days without food or shelter, likely resulting in its demise, presumably, by fox or coyote.When i realized this i fixed the gasket and monitored the situation only to find it to be no hindrance to wildlife in subsequent intrusions. Moreover, as pictured, the door even stayed open when forced by a larger critter making it even less functional...I would not recommend this door for barn cats or in any setting where wildlife pressure is mild or greater.Obviously i am a sad about the loss of my cat that i raised from a kitten and am now responsible for its death because of trying to automate the door. I could have returned this in the return window because my cat was dead before it had lapsed but i couldn't dedicate the headspace to this because of my feelings.If you are not able to check this door every day i would not recommend it
