I know it's technically considered an "issue," but I love strays spawning with full, normal seeming human names so much that I made an account just to comment on it. It brings me so much joy. I just love when my sims adopt a pet and it's like, "Hello, I am Christie Shin and this is my cat, Suzuki Watanabe."
Even if you eventually find a fix for this "issue," I sincerely hope there is an option to keep it.
Also the whole rest of the mod is great too! Thanks!
