Regurgitating

I bought her some expensive healthy non grain small pebble about as big as a bee-bee but she 

can or won't chew them but swallows them whole and last night she left a pile of them with an

undigested huge piece of weed grass.  When I feed her Friskies Seafood Sensations (god forbid) she

is able to crunch and chew them and they seem better for her.  Why is she throwing up the healthy 

stuff and keeping down the junk?

If she threw up soon after eating then it simply means she ate too fast. Maybe the new food was so yummy that she pigged out a little 

Its very common for cats to swallow kibble instead of chew/crunch it. I wouldn't worry about that at all.

Just one point - if your girl is used to Friskies, its important to do a gradual changeover over a few weeks. The two kibbles are very different, and if you go too fast she could get an upset tummy.

I agree with Columbine! 

But I would also add a thought. Could the vomit also be associated with the weed grass?  The weeds we have are very thick; meaning the blades may be too tough for her to die digest.. She may not have been able to handle them...I think Kitty Grass is much better. It is finer and easier to digest.

Yes, I would transition her slowly. Cats do swallow treats whole.. even dry food whole....

It is good that you are trying the new food.It seems more nutritious that the Friskies... although there are many people who feed Friskies and Fancy Feast..

It is easier to transition from wet food than it is from one dry kind to a another. Especially when it is so different..

I think the issue was the weeds..

For a transition from one kibble to another it should be slow going....a bit at a time and mixing it up a bit...

How old is she anyway? and a picture and name are always great!
