Well I went to my local pet store today to look at rats because I've wanted one for a long time. The only problem is that I dont know what I should look for when getting a rat. The guy said that there were only 2 sizes he had big and jumbo. I said jumbo because I wanted a bigger rat, he then asked if i wanted one for a oet or for feed. I said for a pet and he offered me one in the large categorie that was 2 years old. Isnt that a bit old? Well advice is needed should I get a large or jumbo (Im pretty sure i want the jumbo, though) but any other advice would be appreciated!
