My cat has kidney disease and high phosphorus. Can aluminum hydroxide help?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 9 lbs

Hello. My cat is at about stage 3 renal failure. Her phosphorus level is quite high. Have repeatedly tried renal foods but very difficult to get her to eat it. I have read that aluminium hydroxide, Alu-Cap brand name, can be quite effective at lowering phosphorus levels. Do you have any first hand knowledge of this please? Thanks very much for your time.

Poor OIiva! I would certainly get her started on a phosphate binder like aluminum hydroxide if her phosphorus is high. Their is a liquid form but most cats don't like it. I would try the capsules as your mentioned above or have it compounded into a liquid that has fish or chicken flavor. Your vet should be able to help you with this prescription. I would also talk to your vet about starting her on daily or every other day subcutaneous fluids. If she is a cooperate patient, fluids would help to flush out her system and keep her kidney values and phosphorus down and therefore allowing her to feel better. Finally I would talk to your vet about an appetite stimulant if she isn't wanting to eat. I hope this helps!
