This is an awful product, firstly, the batteries were the wrong way round and it didn't come with a tab so I had to unscrew it to even turn it on. The packaging is in very bad English and difficult to understand the instructions. When you set the time, the seconds go too fast so it ends up adding about 15 minutes onto every hour. I have had 2 pets that have both done exactly the same thing, I was able to do nothing but feed and clean up after it for about 20 minutes (if that) and then they both fell asleep, when I went to check on them later they had both died. Do not buy, there aren't even 49 pets so even the name of it is stupid.
