I recently lost both of my parents, which required a drive from NJ to FL with their cats. I had three cats, but we lost Luke (15) in March 2022 and then Piggy (15) shortly after him last year. This left the baby, Lizzy (now 2), as lone cat since then. She and Luke never really jived, but she and Piggy mostly got along.
She is not happy about new cats, and we have them in separate parts of the house. I think Lizzy and Possum will be fine, but Tippy is about as happy about Lizzy as the other way around. Like, hissing & growling when they glance each other through the gate we have up (often covered with a blanket).
Any helpful advice? I really want to avoid having to rehome these two cats but also can’t keep them all separate forever.
