Three-Piece Set for Welcoming a Cat - Product Name: Water Dispenser - Included: Replacement filter 2.8L large capacity, no electricity required. The filter is a used type, but there are 8 new ones, so you won't need to buy any for a while. - Carrier: Cat carrier - Color: White x Blue My cat is 4.7 kg and it's a bit tight, but I think it would be roomy for cats around 3-4 kg. - Cat Toy: Catch Me If You Can 2, Electric Cat Toy Two feather attachments were included, but the feather one is broken, so there's only one left. You can also buy replacement attachments. Especially the carrier has some cat hair on it, but I will clean it as carefully as possible before shipping!! Since I've only used each item 2 or 3 times, it's a much better deal than buying them new!! Of course, kittens are welcome, but so are adult cats!
