Hello! We recently adopted two kittens but for reasons that are too boring to detail here, we could only take one home on Monday and her sibling will be coming home tomorrow (Thursday). They’re both female, both 9 weeks, but I’m having the standard late night overthinking, worrying that the few days gap will mean they no longer ‘know’ each other and will struggle to settle well. Our first little kitten has settled in so well already so I’m hoping it won’t be too stressful for her. Any advice or words of wisdom please? X
