Can Cats Eat Grapes? — No, They Can’t

Grapes are a pop­u­lar and deli­cious fruit enjoyed by humans, but it’s impor­tant to note that they are tox­ic to cats and should nev­er be fed to them. Even though cats may be curi­ous about the sweet taste and juicy tex­ture of grapes, their con­sump­tion can lead to severe health issues and even fatal con­se­quences.

Is It Safe for Kittens to Consume Grapes?

Just like adult cats, kit­tens should nev­er be giv­en grapes to eat. The tox­ic com­pounds found in grapes affect cats of all ages, and their young and devel­op­ing bod­ies may be even more sus­cep­ti­ble to the harm­ful effects. It is cru­cial to keep grapes and any prod­ucts con­tain­ing grapes out of reach of kit­tens to ensure their safe­ty and well-being.

Risks Associated with Feeding Grapes to Kittens

Feed­ing grapes to kit­tens can lead to var­i­ous risks and health issues. The tox­ins present in grapes can cause acute kid­ney fail­ure, which can have dev­as­tat­ing con­se­quences for the kit­tens’ health. Addi­tion­al­ly, symp­toms such as vom­it­ing, diar­rhea, abdom­i­nal pain, decreased appetite, and lethar­gy may occur.

Why Grapes are Not Recommended for Cats

Toxic Substances

Grapes con­tain cer­tain sub­stances that are tox­ic to cats. These tox­ins, such as resver­a­trol and tan­nins, can cause kid­ney dam­age and fail­ure in cats. Even small amounts of grapes or raisins can be detri­men­tal to a cat’s health, so it’s cru­cial to avoid feed­ing them to your feline com­pan­ion.

Gastrointestinal Upset

Even if a cat does not expe­ri­ence severe tox­i­c­i­ty from grapes, it can still cause gas­troin­testi­nal upset. Cats may expe­ri­ence vom­it­ing, diar­rhea, abdom­i­nal dis­com­fort, and loss of appetite after con­sum­ing grapes. These symp­toms can be dis­tress­ing for cats and may require vet­eri­nary inter­ven­tion to alle­vi­ate the dis­com­fort.

Unknown Sensitivity

Each cat is unique, and their sen­si­tiv­i­ty to cer­tain sub­stances can vary. While some cats may con­sume grapes with­out show­ing any imme­di­ate symp­toms, oth­ers may expe­ri­ence severe adverse reac­tions. It is always bet­ter to err on the side of cau­tion and avoid feed­ing grapes to cats alto­geth­er.

Known Health Issues in Cats from Consuming Grapes

The con­sump­tion of grapes by cats can lead to sev­er­al health issues, includ­ing:

  • Kid­ney Fail­ure: The tox­ins present in grapes can severe­ly dam­age a cat’s kid­neys, lead­ing to acute kid­ney fail­ure. This con­di­tion requires imme­di­ate vet­eri­nary atten­tion and can be fatal if left untreat­ed.
  • Gas­troin­testi­nal Upset: Cats may expe­ri­ence vom­it­ing, diar­rhea, and abdom­i­nal dis­com­fort after ingest­ing grapes. These symp­toms may per­sist for sev­er­al days and can cause dehy­dra­tion and mal­nu­tri­tion if not addressed prompt­ly.
  • Decreased Appetite: Con­sump­tion of grapes can lead to a decreased appetite in cats. This can result in weight loss and nutri­tion­al defi­cien­cies if the cat does not resume their reg­u­lar eat­ing habits.

What to Do If a Cat Has Consumed Grapes?

  • Action 1: If you sus­pect that your cat has con­sumed grapes, con­tact your vet­eri­nar­i­an imme­di­ate­ly for guid­ance. Pro­vide them with infor­ma­tion regard­ing the quan­ti­ty ingest­ed and the cat’s cur­rent symp­toms.
  • Action 2: Fol­low any advice giv­en by the vet­eri­nar­i­an, which may include induc­ing vom­it­ing or admin­is­ter­ing acti­vat­ed char­coal to pre­vent fur­ther absorp­tion of tox­ins.
  • Action 3: Mon­i­tor your cat close­ly for any changes in behav­ior, appetite, or signs of dis­tress. Keep them well-hydrat­ed and offer eas­i­ly digestible food, if advised by the vet­eri­nar­i­an.

Safe Alternatives to Grapes for Cats

Instead of grapes, there are sev­er­al safe and healthy alter­na­tives you can con­sid­er for your feline com­pan­ion. Some suit­able options include:

  • Fresh cat-friend­ly fruits like sliced apples, bananas, or blue­ber­ries (in mod­er­a­tion).
  • Cooked lean meats such as chick­en or turkey, ensur­ing it is bone­less and free from any sea­son­ing or addi­tives.
  • Cat-spe­cif­ic treats avail­able in pet stores that are for­mu­lat­ed to meet their nutri­tion­al needs.


In con­clu­sion, grapes should nev­er be includ­ed in a cat’s diet. The tox­ic sub­stances present in grapes can lead to severe health issues, includ­ing kid­ney fail­ure, in both adult cats and kit­tens. It is essen­tial to pri­or­i­tize your cat’s well-being and avoid any poten­tial risks asso­ci­at­ed with feed­ing them grapes. Instead, opt for safe alter­na­tives that will pro­vide nutri­tion and enjoy­ment for your feline com­pan­ion.
