Hi guys! We have just gotten our first rescue, three wonderful girls to add to our already existing pair. We have already consulted all the available info on introductions and came up with a plan (a bit later in this post), but today's event put everything into question and frankly, threw me a bit under the bus. The thing is, we took the rats from the shelter where they were for a full year, so all three of them (Agnetta (Netti), Frieda and Ingrid) are adults and have established themselves as rats. The problem is, however, that Ingrid was born at the shelter and therefore, did not have any human contact. Yesterday when I brought them home we have transferred into the top half of our Savic (similar to critter/ferret nation), and we left them be for the day. The two older sisters are very good with handling and today even don't squick when picked up, take food off the hand and also enjoy some cuddles. Ingrid, on the other hand... Well, when I came in the morning to check on them (they live in our dining room) Ingrid was out and the moment I came to say hi the panic ensued. But it wasn't terrible, and she sniffed my hand before jumping her way to the sputnik at the top of the cage. I took to working at the dining table today to keep an eye on the situation (a thin plastic platform between the halves is not instilling a lot of confidence), so I got a chance to interact with the new girls a bit more as well as letting out oldies have a bit of cuddle and play. Ingrid took a sunflower seed out of my hand, and I was happy that we seemed to be on the right track. However, a couple of hours later the sputnik collapsed under the weight of three rats, I think they had a wee squabble which brought it down as a result. I gave them a few minutes to calm down (and to get zip ties to tie it back up), but the moment I opened the cage Ingrid freaked out, and by this I mean ran, jumped, squealed and so on. I didn't even have time to react to how she was out of the cage! It would be worth mentioning that our lounge is adjacent to the dining room without a door, so you can imagine how stressed I was! There was no way that she'll make it into the cage on her own, and definitely, she couldn't be left out alone. So in a combined effort of my husband and me, we caught her (he got bitten in the process). I caught her into a fleece blanket and released into a small quarantine cage where she presently is right next to me as I type this. I am currently weary of releasing her into the big cage with others as I don't want the incident to repeat, and I don't want it to be imprinted on her that home is not a safe place and I think being closer to us would help her understand that we are not all that bad (although she probably hates us now and might never recover). This is a difficult situation and be she a larger animal or not social as they are I wouldn't be very concerned as the situation would be easy to dissolve. However, we need to proceed to intros soon, as, again, the other rats are very curious about each other and our girls at the bottom are quite strong and athletic so I'd rather they meed in a controlled environment. Our plannes for intros are a healthy combo of neutral territory and carrier method. They are all going to be put in the bathtub first to see how the interactions and figure out compatibilities and so on, and then we'll jump to the carrier method. However, we can't do it, because... Ingrid! I want to sort this mess out as soon as we can, but at this point, I am entirely at a loss. I would love for all of them to have a good, happy and healthy life, especially after a year in a dull shelter cage, and I am going to do all I can to provide it. P.S. Our rat Lila used to be very skittish, but not this much, and we got through it by constantly being there for her and having a lot of contact time, which seems impossible with Ingrid right now.... TLDR. Very skittish new adult rat that is not used to humans escaped the cage, head to be caught. How do we proceed to intros with other rats? She came as part of a trio.
