Cephalexin for cats has been found to be effective at treating these conditions when other antibiotics have failed or have caused negative side effects in your pet.

Cephalexin comes in 250 mg tablets and can be given orally or intravenously, depending on the severity of the infection.

The dosage for cephalexin for cats depends on their weight. For example, for a cat that weighs 10 pounds, you would give them 1/4 of a 250mg tablet every 12 hours (i.e., 2 times per day). If your cat weighs 20 pounds, it would receive half of a 250mg tablet every 12 hours (i.e., 2 times per day).

Active Ingredients

You can give your cat Cephalexin (ke-fa-lex-in) if he suffers from an infection caused by bacteria. Cephalexin belongs to a class of antibiotics called cephalosporins, which are used to treat bacterial infections in cats.

Cephalexin is an antibiotic that treats bacterial infections in cats and dogs. Cephalexin is used for several types of infections, including kidney stones or bladder stones caused by certain bacteria; skin, urinary tract, or lung infections; pneumonia; diarrhea caused by E. coli bacteria; Lyme disease (an infection transmitted through ticks); stomach ulcers caused by Helicobacter pylori bacteria and other gastrointestinal disorders including upset stomachs related to food poisoning


Cephalexin is available in tablet, capsule, and solution form. The dosage for cats depends on the severity of the infection and whether or not your cat has any other medical conditions that impact their response to treatment. For example, a pregnant cat should be given cephalexin only if absolutely necessary because it can cause fetal abnormalities and birth defects.

A typical dosage for humans is 250 mg per day given once every 12 hours but consult with your vet before administering these dosages yourself since cats react differently than humans do when it comes down to taking pills.

Cats are typically given 50mg to 75mg per lb of body weight daily for 7 days or less with food according to the guidelines set forth by the American Association of Feline Practitioners (AAFP). Most veterinarians recommend giving your cat 1 pill at a time twice daily until they have completed their entire course of medication; however, some veterinarians may recommend dividing up each dose into two smaller ones so that you don’t have trouble getting your pet down without any fussing or fighting back from him or her (which could end up hurting both parties).


Cephalexin is a prescription medication, which means that it can only be used under the supervision of a veterinarian. Cephalexin should not be administered to pregnant or nursing cats. It should also not be given to cats who have kidney disease.

If you have any questions about the use of cephalexin with your cat, you should contact your veterinarian before administering it.


Cephalexin is known to interact with several other drugs. It can interact with the following:

  • Other antibiotics, such as amoxicillin and sulfa drugs.
  • Blood pressure medications, such as ACE inhibitors.

It’s important to let your veterinarian know about any medications, over-the-counter drugs, vitamins, or supplements your pet is taking prior to having surgery.

Side Effects

The most common side effects of cephalexin in cats are diarrhea, vomiting, and nausea. If your cat experiences any of these symptoms call your vet immediately. Other possible side effects include:

  • Increased thirst
  • Fever or chills
  • Tenderness around the injection site

If your cat experiences any of these symptoms, contact your veterinarian immediately.


  • Cost:

The cost of Cephalexin varies widely depending on the drugstore you visit and the dosage. In general, you can purchase a generic version of this antibiotic for around $20 per bottle at Walmart or Target. If you want to buy it online (which I do not recommend), it’ll cost about $45 for a one-month supply. The human version will set you back anywhere from $10 up to several hundred dollars per bottle depending on where you go and what brand name medication you want to buy.
