3 weeks delivery to Belgium which is great because I was expecting 2 months. I bought both size S and M because I wasn't sure which size would fit. If you are buying for a cat, definitely take size S - even if you have a big cat. Cat in photo is 7kg, so definitely not a small cat. He is wearing size S and there were still some spare holes on the collar.
Excellent collar, the quality is very good, the only thing, there is no other ring to remove the "tail", but this is not a problem. I ordered the size of m for the puppy beagle (3 months), sat perfectly, i think that enough more for a long time. Length ~ 42 cm. I'm happy! Dog too)) In the sock is also excellent, let's see how much will last.
