Simone is a 7 month old Siamese mix. She has been to the vet 3 times in the past 4 days. They are recommending exploratory surgery as the next step, please read her story to help me decide if this is best. Over the past week, we have noticed that she is walking a little funny, as if her back legs weigh 10 pounds. She will walk a few feet and lay down or sit. She has been licking around her lower abdomen, legs and genitals. She is very lethargic compared to her old self. She has thrown up 3 times in the past week, some regurgitative, some violent and heaving (though still containing food). Upon examination, the vets have found nothing. Her blood work was perfect, they could detect no pulled muscles or pain upon palpating her stomach. She had a bit of a temperature which has returned to normal. The x-rays turned up nothing too unusual. Her large intestine was filled with feces, which she has yet to pass. It is believed that she may have swallowed something like a string, though nothing obvious showed up on the x-ray other than some suspicious gas pockets. (It is very possible that she has considering the toys that she plays with and the new cat condo we just bought had many strings that I caught her and her brother chewing on). I know she is not well, but is it really best to cut her open in HOPES of finding something?? She is my world, please help me. Thank you for your wisdom and time.
