I am having one of my cats pts today due to cancer and I am worried how my other cats will react

[Oldsu]

I have 3 cats Alfie and Maisie are brother and sister and also mum and dad to Harvey, they were my sisters cats.

They spend most of their time in separate parts of the house but do interact and will snuggle up to each other - Alfie and Maisie are 11 and Harvey is 10, I have had them for 8 years.

We are losing Alfie today and I am wondering how the other 2 will react, will they miss him and pine for him or will it not register with them that he has gone?

I don't want to cause them any stress so do I do something to help them or just leave them to 'get on' with things in their own way

And advice welcome

Sorry you're having to lose him . Letting the other cats see and sniff the body is supposed to help them understand. If you are having him PTS at home then logistically it's easier.

So sorry. I took my cats sister to the vets with her when she was PTS.
While we waited for the vet I cuddled Maia, then when she'd had enough of that. She went for a nosey round the room and then climbed into her sisters basket and sat on top of her. I then put Magic on the table and cuddled them together. It was absolutely perfect for Maia. She was calm because she had her sister with her.
After Maia died she sniffed her and instantly recoiled. She knew straight away and never looked for her. It also really helped me, not to be leaving the vet completely empty handed. It was really sad but absolutely perfect for Maia.
Magic was very clingy but as soon as I got my new cat, she visibly relaxed and she's blossomed.

Oldsu so sorry to hear about Alfie. Even though you know it's right, it's such a hard decision to make.

We previously had a brother and sister, so appeared to hate eachother. We weren't comfortable with bringing Toby back from the vet for Lottie to see. She was okay for 24-36 hours but then kept going to the back door, looking outside and then for about three weeks you could tell she was looking for him (not constantly). Other than that she was ok in herself, eating normally, wanting attention, going out.
