Green Kitty Hot Water Bag with Cover

I was so happy to receive this hot water bottle to help treat my chronic abdominal pain, period cramps and muscle soreness. It has become a part of my everyday routine, as it is quite effective.Benefits: I feel instant comfort every time I use this hot water bottle. The warmth helps relax my muscles and provide a steady form of heat when I go to sleep that I’ve found helps me fall asleep faster, as I relax quite quickly. The hot water bottle stays warm for much longer than my homemade hot compresses and is quite comfortable to use sitting up or laying down. It also helps that it’s fluid so it lays and forms comfortably against my body.How To Use: The instructions on the lip state: “Do Not Use Boiling Water Fill Not More Than ⅔ Full And Expel Air Ensure Stopper Is Securely Fixed Store Empty And With Stopper Removed”. It’s clear to advise you not to fill it with boiling water from a kettle, just hot water from the faucet. However, I find that just filling it with just hot water from the faucet does not get it hot enough to my comfort (your comfort level may differ so please try it first). So I usually fill it around ¼ full of hot faucet water and almost ¾ full of water from the kettle that I let steam but never boil to a whistling point. As advised above, it’s important to leave at least ¼ empty at the top in the hot water bottle to allow for pressure changes with the temperature of the water, so I fold that top part over to expel any air before screwing the cap on. I never lay it directly against my skin. I always have my clothing as a barrier between my skin and the hot water bottle to decrease any chance of burns.Storage: Store empty without the stopper in it so it can breathe. I store mine under the sink laying flat with the stopper next to it.Caution: There is a danger in burning yourself when pouring water in from a kettle if it’s just boiled so be sure to pour out some into the sink away from yourself then pour into the hot water bottle to avoid the sudden burst of boiling water that can scald your hand. Of course you can also spill on your hand if you have poor aim or pour too quickly so be sure to be careful and pour very slowly. I’ve read on other websites that using hot kettle water in your hot water bottle will wear it out faster as it is not good for the natural rubber. But as this is the purpose I bought it for, I find that the benefits outweigh that risk. But you may feel differently so just be advised. One warning on the lip states: “Warning: Hot Water Bottles Can Cause Burns Avoid Prolonged Direct Contact With The Skin”. Solid advice.Pros:-Helps Me Sleep-Helps Me Relax-Great Color Selection-Helps Relieve Muscle Soreness-Comfortable to Use Sitting Up or Laying Down-Has Never Leaked/Stopper Has Never Come Loose-Rubber Design Comfortable & Easy to Grip For AdjustingCons:-Using Hot Kettle Water May Wear It Down Faster-If You Put Too Much Hot Kettle Water in it May Burn You (The Rubber Does Get Quite Hot So Be Careful To Find Your Comfort With Hot Faucet Water/Kettle Water)I have yet to use it with cold water as it is still winter so I’m not sure how it serves as a cold compress. But from what I’ve experienced with using it as a hot compress I feel confident it won’t disappoint.

Not too much to say, as it is what it is. Just a traditional product doing exactly what it is needed for. By buying this product you can be sure you are doing the right thing to keep the water hot while using it to relieve your pains or just keep yourself warm.

10/10 is an old-fashioned hot water bottle.

We used them all winter. Worked great. Bought two of them.

Lede:I bought this water bottle in March 2023, and last night—June 2025—I noticed “puckering” on the side. The rubber felt “thin,” and it finally failed. Thankfully, it happened over the sink, so no mess (whew!). This is *NOT* a complaint—two years of near-daily use is a solid run.More:I feel a bit silly reviewing a hot water bottle… but we use these constantly—literally every night.To be honest, using a $10 item this often and for this long is pretty impressive.(*Mileage may vary, of course, but ours got **a ton** of use—muscle aches, arthritis, general warmth, and everything in between, by every member of the family for a variety of needs.)Pro tip: To help the bottle last longer, apply **gentle** pressure to the bottle’s sides when filling with hot water. Fill until water is *above* the internal fill line (halfway inside the flared chamber), then tighten the screw cap until sealed— water should remain in the flared chamber when doing this. Once secure, empty the excess water. (Trapped hot air expands inside the bottle, so reducing excess air inside helps prevent long-term damage.)*This review was written by a real person (me!).
