In my experience it's easier to introduce a new cat when they are young; they seem to accept each other better when they're little. Yuan and Maggie were both adults when I adopted them. But for instance, my cat Deidre (she has since crossed the Rainbow Bridge) and my roommate's cat Boogie were introduced when Deidre was about a year old and Boogie was maybe a couple of months old, and they became best friends:
En mi experiencia, es más fácil presentar un gato nuevo cuando es joven; parecen aceptarse mejor cuando son pequeños. Yuan y Maggie eran adultos cuando los adopté. Pero, por ejemplo, mi gato Deidre (desde entonces ha cruzado el Puente Arcoíris) y el gato de mi compañero de cuarto, Boogie, fueron presentados cuando Deidre tenía alrededor de un año y Boogie quizás un par de meses, y se convirtieron en mejores amigos:
Deidre asserted her authority for a couple of weeks, like, "I'm the boss, new cat" and Boogie said "OK" and then they were friends. Slept together, ate together, bathed each other, played together, everything. :)
Deidre afirmó su autoridad durante un par de semanas, como, "Soy el jefe, gato nuevo" y Boogie dijo "Está bien" y luego se hicieron amigos. Dormíamos juntos, comíamos juntos, nos bañábamos, jugamos juntos, todo. :)
oum... so the more time that passes it will be more difficult for ikki to adapt to a partner 💔 in our room there is hardly any room for ikki, so I do not even think about bringing another cat here, I do not want them to be uncomfortable 😔 So cute that you see in that photo Boogie and Deidre 🥰I also imagine that it is easier when one of the cats has a more submissive personality than the other 🤔 my sister had some cats that were like Boogie and Deidre (they were little brothers), they did everything together and it was very nice, unfortunately one passed away and it was very hard for his brother to overcome his death 😞
It might be okay to introduce a new cat later, I think it depends on the cat. Deidre was the Queen of any group she lived in (when I moved back home with my parents for a while, even the German Shepherd dog was afraid of her. She had just asserted her authority for about a month, and then did the same thing as with Boogie: "Okay, now that you all know I'm the boss, let's be friends" - but by that time they were afraid. Boogie, however, was fearless. She once jumped on a piece of wood as it was being cut with a power tool. No fear!). So probably if Ikki is a bit older but you find an adventurous new cat, they might be ok. ;)
Wow, Boogie was really reckless at that time 😲 the problem is that I think I would end up joining ikki with my sister's cat who is much older ... I hope they get along 😶 so I hope they can sterilize both of them So that this process of getting to know each other is not so aggressive, because they both have their character, I think that happens when you have such spoiled cats ha ha 😅
