DS1 turned 4 this August. He never displayed any allergies to anything apart from the odd few patches of dry skin when I started to wean him at 6 months, and which I could never link to a particular food. They cleared up completely when he turned one.
This May, however, he suddenly came over all hay-feverish - had a permanent runny nose and dark circles under his eyes. After a month or so of this, I took him to the doctor's and we were referred to an allergy specialist who did blood tests which revealed high levels of allergy to tree pollen, cats and meadow grasses. The allergy specialist told us to get rid of our cat immediately and keep all windows etc. closed during the pollen season.
I was pretty devastated about the cat (who pre-dates DS) but started making enquiries about what I would need to do to send him to the UK to my mum's (we live abroad, Eastern Europe). While I was making these enquiries, however, DS's symptoms sort of cleared up and had pretty much disappeared completely by the end of June - despite the cat continuing to live with us.
Five months on and I still monitor DS1 daily for any signs of a reaction, but apart from the first 10 minutes after he wakes up in the morning, when his nose does seem a bit blocked, he is showing no other signs. His nose is usually completely clear by the time he has had breakfast and washed his face.
Today I saw the doctor again for a routine check-up of DS2. She asked specifically about whether we had rehomed the cat, and when I said that we hadn't, and told her about DS1's lack of symptoms, she intimated that we were being irresponsible and that DS1 could become asthmatic if we didn't.
Obviously, the LAST thing I would do would be to endanger DS1's health in any way, but OTOH I don't want to have to rehome the cat (at huge cost, both financial and emotional) if DS genuinely doesn't have any reaction to him at all.
WWYD? Would be grateful for the views of anyone who has been through something similar.
