Petmate Replendish Automatic Gravity Waterer for Cats and Dogs, BPA-Free, No Batteries Required, Includes Charcoal Filter, 0.5 Gallon,Silver

An Easy-To-Clean Water Dispenser
The reason I bought it, and why I like it, is because it has a wide mouth opening on the water bottle. This allows me to easily and thoroughly clean the bottle every week. It takes a few minutes. Additionally, if you like filtration, it has an activated charcoal filter at the bottom which is extremely easy to take out, clean, or replace. Also, you can remove it if you don’t want it. Usually you can use the activated charcoal filters for a long time, and they can be re-charged by boiling them for a few minutes in the microwave. On top of the highly functional design, it is inexpensive. I wish it was stainless steel, but I can live with the way it is. That’s it, but if you are interested, I have more comments in support of this type of water dispenser for cats, which you can read below (or not).The biggest problems I have had is to keep the water fresh in the dispenser for a week at a time, and to get a through cleaning at the end of the week. I also do not need a large sized container because that just wastes water for the one cat, or even two. The usual dispensers of the type we are discussing here have a very narrow mouth. It is practically impossible to get a through cleaning. Gunk builds up on the sides and near the mouth; it can’t be good for your cat. I had even more buildup with the battery powered fountain type of dispensers. Here the bowl is easy to clean, because it is not a narrow neck bottle. It takes me about 45 minutes to clean the two of the battery powered fountains every week because the buildup in in the tubes and narrow places. On top of that, it is not a fun job. My cat is also ambivalent about the fountain vs the regular bowl. When the power goes out for a day or two, you have to use an alternate. I have decided that the powered water dispenser, as good as it sounds, is actually not a good thing because it cannot keep the water fresh. With the one we are talking about here, you can change the water every day if you want – it takes no more time than it takes to get a glass of water for yourself.

This thing is huge, bring muscles.
We have 2 golden retrievers that can drink a crap ton of water per day. We had a 2 gallon water fountain and they would literally drink that thing dry before evening, which then would run the pump dry, which then broke the pump. After a few rounds of CPR on the 2 gallon water fountain….. my partner ordered this 4 gallon water feeder.Let me start by saying…. this thing is massive. It’s a giant dog water barrel water keg. And I’ll add to that by saying this: one gallon of water = 8.34 pounds. X 4. = 33.36 pounds. THIRTY THREE POINT THREE SIX POUNDS of water in a keg. That you are going to PICK UP like a fat greased pig and FLIP OVER aiming the lid (which does not prevent water from coming out)…. aiming that into the properly aligned notches…. And then TWIST to lock it in.Sounds super easy.It goes more like this….. keg runs dry. You unscrew the barrel while steadying the base with your feet. No problem. Unscrew the lid and set it to the side. Clean the keg so your dog has clean water. Fill the keg on the counter by stretching your kitchen sprayer over to it (bc you can’t pick it up out of the sink without causing a hernia). After about 5 minutes of water running, your keg is full. You clean off the lid and screw that back on. Right about now you’re feeling confident… until you go to pick this keg of water up off the counter… then the awkwardness of the whole ordeal is suddenly realized. You may set the kegger back down and try a different approach. Feeling certain this new way is an improvement over your first attempt you will waddle on over to your dog bowl looking something like a mother carrying triplets. You arrive at the bowl (which was a whopping 3 steps on a regular day but 10 shuffles carrying this thing). You look at the bowl and plan your descent, visualizing all the ways this could (and will) go wrong. You decide on the controlled approach, but as you make an attempt at this bright idea you realize your kid will not hold the water in when it is upside down and your give the wall a little shower. No biggie, it’s by the down bowl and probably needed a little cleaning anyway. 2nd attempt – the pigeon kneed flip over…. It sounds as wild as this one will go. You squat with your knees together, thinking your knees can support the weight as you adjust your grip for the flip….. aaaannnnnnndddd nope. You drop the whole keg and water is peeing out the holes in the lid and gushing out from around the filter. You scream, scramble to right the keg and stop the flow of water onto your kitchen floor. You curse a little and clean up that mess. Then you realize you still haven’t placed the keg into the water bowl, and the thing is now ON THE GROUND by your feet. Ugh. This time though, you’re wiser. You study the lid and formulate a plan. You get close as possible to the front of the water bowl, line up the notches on the lid to the notches inside the water bowl. And 1-2-3 oof. OMG OMG. Ok. Not too much water. But now what?! Aaaaahhhhh!!!! Hurry up hurry up!!!! SCREW IT IN!!!! And BLOP! The thing is seated. Gulp gulp gulp. The water bowl starts to fill up. Dogs come running at the sound. And you’re standing there wondering how in the world this could be made easier. Hahaha.So. The pros, this thing holds enough water for 2 golden retrievers for 2 days. That’s a fast enough turn over to not spoil the water and a slow enough return that I’m not having to fill this thing (and repeat the above scene) every 18 hours. The dogs love it. The cat tolerates it but really the water bowl is below his level of class.The cons – it’s big, awkward, heavy, slippery, and takes some planning and a towel or two to execute. I would say, whoever is the strongest person in your household…. this becomes their new responsibility in your home.The good points – pretty much the pros repeated. It holds a lot. I’m not filling the 2 gallon water fountain every 18 hours. It’s easy to clean. It takes little square charcoal filters that go into the lid.The bad points – you need muscles and it’s almost impossible to reseat without a pretty good sized cleanupIf you have big animals and a strong person to do this, buy it. If you don’t…. Go another route.

Our first. Water system did not work and was replace without question and quickly. Keeps dogs hydrated

Love this waterer! I have 3 cats and a large breed dog and it lasts about a week. It’s easy to clean and fill up. Would not have anything else for my animals. It keeps me sane and not worried about them not having water to drink.

This is a good reservoir for the dogs. Initially they were not sure about the taste of the filtered water but now they drink happily. Hopefully the microban will stop it going green so quickly. Plentiful supply in a good deep bowl. One ‘con’ – our garden toad thinks it is great and he can hide completely under the bottle neck. Let’s hope he gets out to pee!
