Sukie (Not a vet) reports the following:
>There was 409 ferret bladder stones with 66.8% of them being struvites,
>14.9% being cystine stones, and 10.5% being calcium oxalate stones. In
>mink all 22 were struvite stones.

Percentages 66.8 + 14.9 + 10.5 = 92.2 percentages total

Stone totals = 92.2 percent of 409 stones = 377.098 stones

and we get the same answer taking the individual percentages

409 X 0.668 = 273.212 struvites (Mostly found in females with urinary
tract infections)

409 X 0.149 = 60.941 cystine (One of the decomposition products of
protein)

409 X 0.105 = 42.945 Ca oxalate (Calcium in combination with phosphates
or carbonates)

Sum total of stones = 377.098, whereas total above is 409.

409 minus 377.098 = 31.902 stones deficit.

Conclusion. 377 stones were assayed for content, but 409 were reported
examined. There appears to be no accounting for 32 stones. Why?

Iksnipil Drawde would be very embarrassed if his simple math is in
error. Even so he shall appreciate learning why there is an error,
either in his math or in the accounting and how it comes to be. List
readers are certainly invited to comment.

In the ferret, what symptoms are recognized as being related to kidney,
bladder or urethra stones other than increased time for a given
urination? Would a ferret squeal in pain during urination if it had
bladder stones? And what is the normal duration urination time?
