I've developed an allergy to the cat. Does immunotherapy work?

[MrsBertMacklin]

I've had BertCat for three years now, unfortunately for the last nine months, antihistamines have proven useless. It's exacerbated by hay fever in summer; I've woken up with a sneezing fit in the middle of the night for four consecutive weeks.

I'm going to stop her from coming into the bedroom, but I really don't want to limit her from sitting in the sofa etc, so I'm looking at immunotherapy. Has anyone had good results with it?

Not sure about that but you could try petal cleanse on the cat

Didn't know that was a thing, thank you.
