Someone on PT also mentioned that they found a great difference in giving their cats filtered water, not straight from the tap (or well). Filtered water has way fewer minerals in it - that could be why!

Oscar had a UTI about a month or two after Cole joined the household - about a year into his stay. However, he had VERY few crystals...the blood in his urine stayed at least a month! So this was due to stress, the new kitty - even though they got along!

They have both been on filtered water since they lived with me...dry is Origen, wet is Royal Canin (now Medi-Cal) SO.

Hope little Robin feels better soon!
