Hi I have a Savannah Bengal mix male and a Savannah Female. Both have had Uti’s in the last couple months. Hers has cleared up his on the other hand has not. Just in the last week he’s been to ER. I have been told he has crystals and they want me to put him on Science Diet SO. What do you think? Do you recommend anything else.? They currently eat Acana Meadowlands. Thanks.
