Warm, Comfy, and No Electricity Needed
Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey
This self-warming cat mat works well — it reflects body heat and stays noticeably warm without plugs or electricity. The surface is soft and cozy, and most cats seem to take to it quickly. It's lightweight, easy to clean, and fits well in beds, carriers, or on furniture. It’s a bit thin, so adding extra padding underneath may help. Also, it can slide on hard floors, so best used on carpet or fabric surfaces.

It's a hit!
Size: 27.6"L x 18.8"W x 0.5"Th, Color: Grey, Size: 27.6"L x 18.8"W x 0.5"Th, Color: Grey
He loves it. I wish I had purchased the large instead of the medium, but it still fits him okay. If he stretches out, it won't, though. :) He's a big boy. I have it lying on a bed in the spare room, where he often is, looking out the window. It's soft and makes barely any noise. It doesn't slip on the bed. I might on the floor. With anything new that we buy him, we spray it lightly with catnip spray and he always takes right to it, as he did with this. It's warm under his body. He's happy, we're happy! :) I ordered the larger one. It got here today! I moved the smaller one to a window seat. I hate when the delivery guys add, was handed directly to homeowner, no it wasn't It was put in a package box outside, ringing the door bell is not the same as handing it directly to me! LOL

My cats love their self heating mat!
Size: 27.6"L x 18.8"W x 0.5"Th, Color: Coffee
I use this as a cover on my loveseat. It took my cats a few days to realize how much they liked their new mat. It makes a little crinkle sound when they walk on it but they don't seem to be bothered by it at all.

Thinner Than Expected but Still Gets Used ULIGOTA Self-Warming Cat Mat
Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey, Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey
This self-warming mat is much thinner than expected, and the corners don’t lay completely flat—they tend to curl upward, which makes it look a little cheap when first placed down. The material is soft, though, and despite its lightweight feel, it does warm up slightly when the cat lays on it. It’s not plush or padded like some other warming mats, but it still provides a cozy surface. Pros: • Soft surface • Lightweight and easy to move • Cat actually uses it • Self-warming layer works to a small degree Cons: • Much thinner than expected • Corners curl up and won’t stay flat • Doesn’t feel premium Verdict: Even though it’s flimsier than anticipated, my cat sleeps on it consistently—so it’s staying. For pets that don’t need much cushion, it’s a decent budget option, but buyers should expect a very thin mat rather than a plush warming pad.

Works just as intended
Size: 20.0"L x 16.0"W x 0.5"Th, Color: Coffee, Size: 20.0"L x 16.0"W x 0.5"Th, Color: Coffee
My recently adopted rescue kitty loves this self-warming mat. We live in the south, and sometimes the temps drop a bit. I placed her mat out onto some blankets and she was immediately receptive to it. I sat and gave her plenty of cuddles while she laid down on the pad, and I could feel the toasty warmth beneath her body on the fabric. The size of the mat you see in my photos is the 16”x20” size. My kitten is 6 months old and she is a gangly, lanky girl. She fits on the mat when curled up- but she likes to sprawl as well. This size is great for inside her travel carrier, but I will more than likely also order a larger size for home use so that I can keep the smaller one in her travel carrier. I ordered the brown and I like the rich, chocolatey color. The top is a very fine micro velvet that is very soft. The underside is polyester that has some small rubber dots for traction. It is thin and very pliable. The mat is great quality and has held up with my kitty attacking it during playtime as well. Whether for home or for travel uses- it’s a big hit with my kitty! Works just as described and makes a wonderful addition for these colder months.
