I have a 4 year old male cat(Lucifer, after the show) that I’ve had since he was maybe 6-7 weeks old. For the first 2 years, he was living with my Fiancé, whom lived in 3 different households throughout those 2 years. And then Lucifer lived with my aunt while I searched for an apartment. Each household had dogs and other cats (both male and female) he got along well with the male cats, but not so much the females. and he loves the dogs. he’s lived with us in our apartment for 2 years now and hasn’t stayed anywhere else. On July 23rd, we decided to take in a 9 week old male kitten. Had I known then what I know now, I certainly wouldn’t have rushed the introduction as, Lucifer was my very first cat and I never got the chance to slowly introduce him to other animals. but unfortunately I was a bit hesitant to leave the kitten in my daughter’s room as she likes to play in there every morning and I was worried she would get into the litter box or the food and water. (she’s 3 and, she still sleeps with me here and there) it’s now July 31st and Lucifer hadn’t eaten in two days, so in an attempt to get him to eat, I set up a litter box in my daughter’s room, placed food and water in there as well as Salem’s (the kitten) toys and little nap basket. and I go up there often to play with him and make sure he’s eating and using the litter box. Lucifer began to eat after about an hour of not seeing Salem. Now that he seems to be doing better, my question is how long should I keep them apart before reintroducing them? Lucifer was my first pet, at 19. Growing up, we never lived in a home that allowed pets of any sort. So having 2 cats was really exciting for me. But now I’m starting to wonder if because I screwed up and rushed the introduction, they’ll ever actually get along or if I’ll have to permanently keep them apart..? Any advice helps!
