Just had a quick update, my vet said I should have seen some improvment in her stools by now and she wants me to switch her food to royal canin green pea and rabbit but i think i'm going to wait until i see the dermotologist to see what she thinks. i'm just worried that her soft stools are from a different problem. I will let you know how it goes. Here is what I'm going to tell the dermotologist does that sound ok?
By doing different food trials and observing when she itches most, to us it seems like her allergy is either an inhaled allergy to something that only flares up when on furnace is turned on, to chicken if it's one of the first few ingredients in canned food or to something in canned food all together.

She's been eating wellness dry since August 21 and not itching bad or breaking out because she is doing so good right now our plan was to keep her on this food until our furnace is turned on to see if see has a flare up but the problem is our vet wants us to change her food to Royal Canin's green pea and rabbit because she's been having soft stool but we're worried about this because she tired Natural Balances green pea and duck and that was too rich for her also we're wondering if there could be a different problem causing her soft stools because she had them when she was on Z/D too and they looked healthy for a while until she had a stool with a piece of hair in it and now she's also urinating more and her urine has a redish brown color to it, we tested her for an infection and it came back negative but is there any blood test or anything we should do before switching her food incase there's an underling problem. I also did read that sometimes natural foods are just too rich for some cats so I didn't know if we should go back to a dry food that isn't too rich.

Here is some background information...

When we got her from the SPCA last June, her papers said she had thinning hair on her trail probably due to an old flea allergy but she wasn't itching or breaking out yet.

We were feeding her Nutro dry food exclusively she was on that for about four months and doing great but then two things changed our forced air furnace was turned on and we started adding Nutro canned food into her diet. In November is when her itching got really bad and she started breaking out in little scabs on her neck and chest, because she only had breakouts on the front part of her body is why our vet thinks it's a food allergy.

We tried switching her food to Natural balance dry and wet food with no grains but that didn't help.

Then in March we started feeing her the Natural Balance green pea and duck soon after she started that she had to go to the emergency vet because she had a block, a vet there said that food was probably too rich for her and her stomach always did look puffy while she was eating it.

Then we did a food trial with Z/D from May until August, she threw up a lot while eating this and her stools were soft then too. When she was eating this her itching was about the same as it was the summer before when she was eating dry food only and our furnace wasn't on.

Now she's been eating Wellness since 8/21. This does have chicken fat and chicken flavor in it but it's down on the list.

Since she was having soft stools we just finished a five day trial of metronidazole last Friday but that didn't help. We couldn't get her to keep the pill down so we had to give it to her in a pill picket and roll it in canned food.

We want to use the least amount of medicine as possible.
If we find out it's just an inhaled allergy and it gets as bad as it did last year is there a safe medicine that she could go on from November to April every year because the other six months of the year when we can have the windows open she's not bad at all.
We don't want to use Depo-Medrol because I read it can send a cat into congestive heart failure very quickly!



Things we have tried to stop her itching...

Prednisolone 5 mg January-May (this only helped when we gave her 1/2 a pill every other day but we didn't want her on it for any longer than what she was on because it can cause problems down the road)

Steroid shot (helped the best but only for one month)

Started using hypoallergenic kitty litter

Feilway diffuser
