hello all! I have three young ratties, two adopted back in February at around a month and a half old and the third, their younger companion around a month old back in April. The youngest, named Aspen, has become really aggressive as of late. From what i’ve been finding on forums and just reading up, I feel like his aggression is due to hormonal changes. But last week he’d bitten me quite deeply two days in a row when I was attempting to move them to a smaller holding cage so I can deep clean the main cage. It wasn’t too deep, but it was hard enough that I bled a lot. Now I try to pick Aspen up, he screams in fear and I worry that there could be something wrong. Earlier this week upon examining the older two, I found their bodies riddled with injuries. All treated and healing well, but I had to wear some gardening gloves to separate Aspen from the group into a smaller cage adjacent to the main one. Although i’ve called a vet to inquire about neutering, it was suggested I wait till he reaches 6 months before scheduling his surgery. In the mean time i’m trying to handle him and try to show I mean him no harm, but I have to stop considering how many bites I now have. (Now 3) I handled Aspen the same amount as my other two, Zephyr and Nico, yet Aspen is the most aggressive out of all of them.
