Hi all, hoping you knowledgeable folk can help. We have a gorgeous nine year old cat that we have had since he was around 3. He was initially very timid and withdrawn but is now just a lovely gent, brilliant with our two girls who’ve arrived subsequently and an all round softy. We’ve agreed to take a new kitten, she’ll be arriving next weekend. She’s around 12 weeks old and spayed, and is a timid little thing also so we’re hoping will be compatible. Any tips on how to introduce her to our old boy please?
