3 days ago my mom found two kittens in the middle of a highway, cars straddling them and driving over. No mom or siblings were anywhere around. I took them to the vet, they are both female and 5 weeks old (I’m sure they are sisters). The plan is for my sister to have one when they are old enough to separate. They have both been staying at my house together these past few days. I am starting to notice that they are 100% best friends. I am getting worried that it might not be OK to separate them at all. I’ve read 8-12 weeks is where they begin being separated from the litter, but these two kittens went through a traumatizing experience together and I think they may be “bonded”. They groom each other, play with each other, eat together, sleep together, everything. My sister will be heartbroken if I keep both because she has already named hers and comes to play with them daily. Is it okay to separate them at some point, or should I push to keep them together? Will their bond subside over time or are they forever bonded? Please help, I am having an intense internal conflict over this.
