Can Cats Eat Flies? — No, They can’t

Cats are nat­ur­al preda­tors, always on the prowl for small mov­ing crea­tures like flies. While it may be enter­tain­ing to watch your cat chase and cap­ture flies, you should not pur­pose­ly feed flies to your feline com­pan­ion. Flies do not pro­vide any sub­stan­tial nutri­tion­al val­ue for cats and can even pose risks to their health.

Can Kittens Eat Flies?

Just like adult cats, kit­tens should not be fed flies either. Their tiny diges­tive sys­tems are not designed to process insects like flies, and con­sum­ing flies may lead to gas­troin­testi­nal issues or oth­er com­pli­ca­tions.

Things to consider when feeding flies to kittens?

There are no ben­e­fits to feed­ing flies to kit­tens, and it is best to dis­cour­age any attempts at con­sum­ing flies.

Nutritional Benefits of Flies for Cats — Why Flies are not Suitable for Cats

Fly Hunting as an Instinctual Behavior

Cats have a nat­ur­al instinct to hunt, and chas­ing after flies allows them to ful­fill this innate behav­ior. How­ev­er, it is impor­tant to note that the act of hunt­ing flies is more about the thrill of the chase rather than acquir­ing sus­te­nance.

Potential Health Risks

Flies can car­ry var­i­ous dis­eases, par­a­sites, or harm­ful bac­te­ria that can be trans­mit­ted to cats through inges­tion. Con­sump­tion of flies can lead to gas­troin­testi­nal upset, vom­it­ing, or even infec­tions.

Nutritional Insufficiency

Flies do not offer any sig­nif­i­cant nutri­tion­al ben­e­fits to cats. Cats require a bal­anced diet con­sist­ing of high-qual­i­ty pro­tein, fats, vit­a­mins, and min­er­als, which are best obtained through spe­cial­ly for­mu­lat­ed cat food.

Potential Allergies: Can Cats Be Allergic to Flies?

Cats do not typ­i­cal­ly devel­op aller­gies to flies specif­i­cal­ly. How­ev­er, cats with exist­ing aller­gies or sen­si­tiv­i­ties may expe­ri­ence adverse reac­tions if they come into con­tact with flies due to oth­er fac­tors, such as insect bites or expo­sure to cer­tain aller­gens present on the fly­’s body.

Symptoms of Fly Allergies in Cats

  • Itch­ing and Skin Irri­ta­tion: Cats may exces­sive­ly scratch or groom them­selves, lead­ing to skin inflam­ma­tion or even sec­ondary infec­tions.
  • Res­pi­ra­to­ry Issues: In some cas­es, cats may exhib­it symp­toms like sneez­ing, cough­ing, or dif­fi­cul­ty breath­ing if they have inhaled aller­gens car­ried by flies.
  • Gas­troin­testi­nal Dis­tur­bances: Aller­gic reac­tions can some­times man­i­fest as vom­it­ing or diar­rhea in cats.

What to Do If Your Cat Shows Symptoms?

  • Con­sult a Vet­eri­nar­i­an: If you notice per­sis­tent or con­cern­ing symp­toms, it is cru­cial to seek pro­fes­sion­al advice from a vet­eri­nar­i­an to diag­nose and treat any poten­tial aller­gies or health issues.
  • Envi­ron­men­tal Con­trol: Min­i­miz­ing the pres­ence of flies and employ­ing prop­er pest con­trol mea­sures can help reduce the expo­sure of aller­gic cats to poten­tial aller­gens.
  • Aller­gy Test­ing: In severe cas­es, the vet­eri­nar­i­an may rec­om­mend aller­gy test­ing to iden­ti­fy spe­cif­ic trig­gers and for­mu­late an appro­pri­ate man­age­ment plan.

Recommended Amount: How Much Flies Can a Cat Consume?

Flies should not be con­sid­ered a part of a cat’s reg­u­lar diet. Feed­ing them flies is unnec­es­sary and does not con­tribute to their nutri­tion­al needs. It is best to focus on pro­vid­ing com­plete and bal­anced cat food that meets all their dietary require­ments.

Things to Consider When Feeding Flies to Cats

As men­tioned ear­li­er, it is not advis­able to feed flies to cats due to the poten­tial health risks and lack of nutri­tion­al ben­e­fits. Always pri­or­i­tize a well-bal­anced cat food diet rec­om­mend­ed by vet­eri­nar­i­ans to ensure your cat’s opti­mal health.

How to Feed Flies to Cats: A Quick Guide

Feed­ing flies to cats is not rec­om­mend­ed. How­ev­er, if your cat acci­den­tal­ly con­sumes a fly or catch­es one while explor­ing out­doors, it is gen­er­al­ly harm­less. Just mon­i­tor your cat for any adverse reac­tions and con­sult a vet­eri­nar­i­an if nec­es­sary.


While it may be fas­ci­nat­ing to watch cats chase after flies, it is essen­tial to pri­or­i­tize their over­all well-being. Feed­ing flies to cats is unnec­es­sary and poten­tial­ly harm­ful, con­sid­er­ing the risks asso­ci­at­ed with flies and the lack of nutri­tion­al ben­e­fits they offer. It is always best to pro­vide cats with a bal­anced diet con­sist­ing of high-qual­i­ty cat food and con­sult a vet­eri­nar­i­an for any dietary con­cerns or ques­tions.
