We probably have to rehome our cat and I'm gutted

My younger kid is 4 and he's always had eczema and asthma. Until recently our doctor told us there was no sense doing any tests, and to keep the cat, because he might grow out of everything before too long. Well, he hasn't yet. All winter we have to put heavy-duty medication on his face to keep his eczema in check. He gets puffers and antihistamines every day. If he gets a cough he throws up for three days because his breathing is so bad.Doctor says it's time to do the allergy test. Kid is probably atopic, which refers to the connection between eczema, asthma, and allergies. 70% of atopic people are allergic to cats, and if he hasn't outgrown the allergy by now, he probably won't.If he's allergic (and I am sure he is), we have to get rid of Joni Mitchell the cat. Our beautiful grey rescue, who is somewhat dimwitted and loves cuddling all day and all night. I know I have to do the test and get rid of the cat, but I can't even bring myself to think about it, it hurts so much. Just another situation where the right thing to do sucks.
