Right after we went to retrieve our cat from it's vacation address we brought her to the vet. She'd been going to the litterbox too often and we also just wanted a little check up in general. Turns out she has urine christals and has to go on antibiotics for a little while and a lifelong diet.
Now what really pisses me off about this is that it is caused by a high salt percentage in cat food! It is quite a common problem with cats simply because their food isn't right for them at all.
I am really quite disgusted that it's apparently still okay in the food industry to say stuff is healthy while it is actually causing harm. I know there are still a lot of issues with food humans eat too, but at least we have a lot of choice. Cat food is cat food and you think you can feed it to your much loved cat, but I guess not...
