To want fiance to get rid of his cats

This!

Try fexofenidine as your antihistamine. You can buy in supermarket or chemist. Boots do own brand version www.boots.com/boots-fexofenadine-hydrochloride-120mg-film-coated-tablets-10-tablets-10357318?traffic=paid.shopping&gad_source=1&gbraid=0AAAAA-AdmwQ2RI676xWb_OZ0ZevDCYi2T&gclid=Cj0KCQjw_dbABhC5ARIsAAh2Z-QFDSEKsMRsrBds8z9w3d5sGPrkcjEgqts9wcjemzOTzyLGSpzpIPQaAuicEALw_wcB&gclsrc=aw.ds

I have multiple allergies and thos works better plus I can top up with loratidine at night if needed

Wow. I think iit might be better if your fiance dumped you. I think this is unnecessarily cruel on your part.

Because dogs are just way more important than cats apparently!! Surely you realise you are being unreasonable.

I would never get rid of my cats. They are my family and I love them . They are my babies.
Why are you expecting your bf to get rid of his "children ".
Why aren't you considering rehoming your dog?

I'm afraid I wouldn't consider taking the bold step of "moving " in to your environment.
Sorry

Lots of people live with cats and have allergies. There have been several posters on here alone testifying to this. The OP has said she is willing to take an antihistamine daily. The allergies are not the issue.

I am a huge cat lover. Your home isn't suitable for two indoor cats, and you are allergic. On that basis, your dp should seek a loving home for them, or stay where he is.

@ellie09 could the cats not have your DPs room as their space seeing as it will have his stuff in? Or is it a full upstairs ban? Would give them a space away from the dog and can spend time with your DP while he works etc

Yes this is what I was trying to say. Everything else you can work around but not the allergies. That’s going to be horrific for you OP.

If you weren’t allergic I would say YABU

But you can’t live in a house with two animals that make your throat close up! That’s madness in my opinion and I’d say it’s up to your DP to either rehome them or keep living separately.

Also, lot of ignorance on this thread about Rotties - they make excellent family pets when well trained and socialised. In my experience, it’s those with smaller breeds that are the most irresponsible owners.

Yanbu - he will be living rent free, you have a dog and allergies - the allergies alone are enough imo

Yes, this. 14-15 years for the average rottie would be shocking.

Your GP will be unlikely to give you stronger antihistamines. They aren’t really a thing. They’ve stopped even prescribing them for kids who usually get them for free. Even my steroid nasal spray that was on prescription they won’t give now. Basically having spoken to a friend who is a GP and allergy specialist an allergy clinic would likely to up your dose of antihistamines. The dose on the box is very conservative and can be increased substantially. Some GPs won’t officially temp you this though. You could ask for a referral to allergy specialist if it remains an issue. The one antihistamine that used to be prescription only is fexofenadine but you can now buy that in many places and I’ve noticed a cheaper generic version out this year which I hadn’t seen previously. Lots have changed to this and got a better relief than their usual.

My DD has animal allergies (as do I) and her hubby is horse rising (she’s tried loads and this is the only one that’s stuck) but she’s allergic. She also has hayfever so doubly hit in the summer. We saw the GP as her allergies were causing nose bleeds. He basically said that we could either increase antihistamine dose or try an asthma medication which isn’t recommended long term but worth a try short term to help stop the nose bleeds. She was on it for about 6 months and her nose bleeds have really calmed down. But her allergies haven’t. She doesn’t take it anymore as I wasn’t keen on the side effect but I’ve a friend with life threatening lung problems and allergies who does take it long term.

I struggle with cats. Even with antihistamines I still struggle. I have a friend who has cats and when I meet her for coffee out in a cafe I can often feel my throat starting to itch and need an antihistamine.

That's absolutely fine. You don't need tons of space. You just need boundaries and training and activity.

I don’t think you’re compatible. I don’t think what you are suggesting is reasonable despite it saving you money to move him in. I would see you as a huge red flag.
All the excuses and the strictness about animals not going upstairs doesn’t sound very loving. Plus your comment about your 6 year old dog being at the end of his life tells me you’re just not an animal person. I say don’t move in together. Go your separate ways

They WEREN'T there before OP. That's the whole point.

How did he know she was allergic to cats when the OP herself didn’t know this?

Well, I can't even see why you two are together, this is going to be a terrifying experience for innocent animals who have done nothing wrong AND were there before you!

I rehomed my much loved cat because once our dc turned up it became clear she was unhappy living in a house with young children. She was showing lots of signs of stress. She went to live with my MIL who kindly took her in and showered her with lots of love and she is much happier in a quiet predictable house with only two adults. All of her symptoms resolved overnight. We visit her still all the time and she still shows me lots of affection when I see her but it’s clear everyone is better off. I don’t get this idea that it’s evil to rehome a cat if they’ll be better off that way! There are lots of people online looking to rehome well-socialised animals including lonely older people who can provide ideal homes for cats, who mostly like quiet and routine. Some of these posts are just ridiculous!

I wouldn't re-home my cats for a man so I wouldn't expect someone to do it for me.

Get a dog trainer in to show you how to teach cats and dog to live together.
It will take a few months but it is not an uncommon problem for trainers. Talk to them Before you move in together.
if necessary you could get a cat cabin for the garden for when you are not there.

Take shares out in an Anti histamine company.

I wouldn’t rehome my cats for anyone.
That said, neither of you have considered the long term commitments of getting animals.
Getting kittens is (hopefully) a 15 years + commitment, did that not cross his mind or yours enough to mention it to him.
consider other options such as getting a catio for the cats so they can have some outside space away from child and dog, or moving in together.
seems like he’s being asked to make sacrifices as he’s moving in with you, would you rehome your dog if it was the other way round.

She is allergic to them

Rotties don't live as long, usually about 9 years.
