My Siamese, Nicky, who is 11 1/2 yrs old, here lately has been vomiting up his dry food. My cats eat the Royal Canin Urinary SO wet & dry food as they have had UA issues in the past & this food seems to agree with them & prevents some UA issues. I normally feed the 1/4 can in the am & 1/4 can in the pm & dry food thru out the day when they insist. On occasion, throwing up dry food is not a problem but here lately, Nicky has been throwing up his dry food on a regular basis, no matter how little I give him & yet he wants the dry food. I plan on taking him in on Wed. when I have to take Mr. Topaz in for a recheck & maybe have some x-rays done as well as blood work even though he appears to be normal as always except for the vomiting. Has anyone else experience this with there older cats?? All my cats are strictly indoors & I always take them in yearly for a wellness exam, blood work, etc.
