So our normal diet we eat 1/4 cup of katz n flocken at 10 am and 5pm, then get an ounce and a half of wellness canned food at 10pm. well Athena recently had an other urine problem. this is the 6th or 7th time of this happening in her 5 years. so we are switching to all canned food (wellness). Obviously the large cans are the better value. so I was wondering how much to feed out of the large cans. so far i've been using up our 3 oz cans. so between 2 cats... an ounce and a half each... so 4 and a half ounces a day. does that sound right? How should i measure this? thoughts on feeding all wet? thanks!
