Quick Answer
While cat food won’t necessarily harm dogs if eaten occasionally, it’s not recommended. Dogs have different nutritional needs than cats, so cat food does not provide optimal nutrition for dogs. Additionally, cat food is higher in fat and protein than dog food which can cause gastrointestinal upset if a dog eats too much. It’s best to stick to treats made specifically for dogs. Dog treats provide the right nutrients and are perfectly portioned.
Nutritional Differences Between Cat and Dog Food
Cats and dogs have very different nutritional requirements, so cat and dog foods are formulated to meet those specific needs. Here are some of the key differences between cat and dog food:
Protein
Cats need a much higher protein percentage in their diet than dogs. Cat foods contain around 26-40% protein, while most dog foods are in the 18-25% protein range. The increased protein in cat food helps cats maintain lean muscle mass. While the extra protein likely won’t harm dogs in the short-term, too much over time can tax their liver and kidneys.
Fat
Cat foods also have increased fat content compared to dog foods. Cats use fat as a key energy source, whereas dogs utilize carbohydrates more. Like excess protein, more fat than a dog needs can cause issues when given long-term. Fatty foods can also lead to pancreatitis in some dogs.
Vitamins and minerals
Cat foods are formulated with higher levels of certain vitamins and minerals cats need. For example, they have increased taurine, arachidonic acid, vitamin A and niacin. Dogs require lower amounts of these nutrients. Too much vitamin A and niacin can cause toxicity in dogs if consumed over a long period.
Carbohydrates
While cat foods are high in animal protein and fat, they contain minimal carbs. Dogs can utilize carbohydrates better than cats, so dog food contains some carbs to provide energy.
| Nutrient | Cat Food (avg %) | Dog Food (avg %) |
|---|---|---|
| Protein | 26-40% | 18-25% |
| Fat | 15-20% | 8-15% |
| Carbs | Under 10% | 25-50% |
As shown in the table, cat and dog foods differ significantly in macronutrient profiles. While an occasional cat food treat won’t cause issues for most dogs, regular feeding of cat food can lead to nutritional imbalances over time.
Digestive Upset
In addition to long-term nutritional implications, the high fat and protein content of cat food can also cause digestive issues if dogs eat too much. Some dogs may get an upset stomach from cat food, including:
– Vomiting
– Diarrhea
– Gas
– Bloating
– Reduced appetite
These signs often develop within hours of eating cat food. Obesity and underlying conditions like pancreatitis also make dogs more prone to stomach issues from fatty foods.
Cat food’s strong aroma and flavor compared to dog food can also entice dogs to overindulge if given access to a bowl. Eating more than their stomach can handle is a recipe for tummy troubles. Monitoring treat portions is important.
Dental Disease Risk
Many cat foods contain smaller, softer kibble than dog foods. The smaller size and sticky texture make it easier for cats to chew with their smaller jaws and teeth. However, these characteristics also make cat kibble less effective for cleaning dogs’ teeth.
Larger, crunchier dog kibble helps scrape away tartar and plaque as dogs chew. In comparison, the smaller cat kibble tends to get stuck on teeth. Over time, this can contribute to more dental disease.
Cat treats also often contain more soft, chewy formats compared to dog treats. Again, these texture differences reflect the dietary needs of cats versus dogs.
Behavioral Problems
Feeding cat food occasionally probably won’t impact behavior for most dogs. However, regularly feeding cat food instead of dog food could cause issues.
For example, the higher fat and protein levels may lead to increased energy levels. This can contribute to hyperactivity, especially in already energetic dogs.
On the flip side, nutritional deficiencies from improper nutrition could also affect energy levels and behavior. Every dog has unique nutritional requirements based on their age, size, and activity level. Cat food won’t meet large or active dogs’ increased needs.
Finally, feeding cat food could lead to begging, counter surfing, or stealing cat food from the actual cat! It’s best not to start the habit at all.
Toxicity Risks
Most cat foods are nutritionally balanced and safe for the target species. However, a few ingredients added specifically for cats could potentially cause issues if dogs ingest them regularly or in large amounts. This includes:
Xylitol
Some cat foods and treats contain the sugar substitute xylitol to help manage feline diabetes and weight issues. However, xylitol is toxic to dogs. It can trigger a dangerous blood sugar crash within 30 minutes of ingestion. Only small amounts are dangerous to dogs.
Increased vitamin D
Cat foods contain extra vitamin D compared to dog foods since cats have higher requirements. While moderate amounts likely won’t harm dogs, excessive vitamin D over time can cause toxicity. Symptoms include lethargy, vomiting, loss of appetite, increased thirst and urination, muscle tremors and seizures.
High vitamin A levels
As carnivores, cats also need increased vitamin A in their food compared to dogs. While occasional ingestion likely poses minimal risk, regularly consuming cat food with very high vitamin A content could potentially cause toxicity in dogs over time.
However, this is quite rare since most cat foods don’t drastically exceed dog needs. Signs of vitamin A toxicity include limping, bone swelling and fragility, weight loss, and abnormal bone growth in puppies.
Overall, toxicity is very unlikely from periodic cat food treats. But it’s safest to verify cat food doesn’t contain any ingredients specifically added for cats that could be dangerous to dogs.
Alternatives to Consider
Rather than providing cat food, most veterinarians recommend finding alternative dog-safe treats. Here are some healthy options:
Dog treats
Giving regular dog treats lets you provide an exciting reward while maintaining balanced nutrition. Search for all-natural single ingredient treats without fillers or artificial additives. Always adjust portions for your dog’s size so treats don’t provide excess calories.
Some healthy options include dehydrated meats like chicken, beef or salmon, dried fish skins, freeze-dried livers, and single-ingredient dental chews. Check labels and avoid treats made in China.
Unsalted popcorn or air-popped popcorn
Plain popcorn makes a nice low-calorie treat dogs love. The crunch provides mental stimulation too. Make sure it’s completely unsalted and unbuttered. Limit portions to 1-2 cups per day for a medium-sized dog.
Flavored yogurt
Plain nonfat Greek yogurt mixed with a bit of peanut butter or banana makes a creamy, high protein treat. Avoid yogurt with artificial sweeteners. Limit to 1-2 tablespoons for small dogs or 1/4 cup for larger dogs.
Chopped fruits and vegetables
Fresh produce like apple slices, diced watermelon, pitted cherries, blueberries, carrots, and broccoli florets provide healthy vitamins, minerals, and fiber. Rinse and chop to avoid choking. Introduce new items slowly.
Trail mix without chocolate or raisins
Dry roasted unsalted peanuts, almonds, cashews, pumpkin seeds, and dried fruits like bananas, apples, or cranberries make a crunchy homemade trail mix. Check ingredients to verify no raisins, grapes, onions, or chocolate, which are toxic to dogs.
Ice cubes
Dogs love chasing and chewing on ice cubes. The cold treat is refreshing on hot days too. Adding water or low-sodium broth to the ice tray provides extra flavor. Limit portions to prevent freezer mouth injuries. Avoid offering too many to smaller dogs or breeds prone to bloat.
Frozen broth in a Kong
Stuffing and freezing low-sodium chicken, beef or vegetable broth inside a Kong toy provides a cooling, hydrating treat dogs adore. You can add in other safe ingredients like kibble too. Supervise to avoid cracked teeth from aggressive chewers.
Key Takeaways
Here are the key points to remember:
- Cat and dog food differs in protein, fat, vitamin, and mineral content to meet different nutritional requirements.
- Too much cat food can cause digestive upset in dogs since it’s richer than dog food.
- Regularly feeding cat instead of dog food risks nutritional deficiencies or excesses over time.
- Some ingredients like xylitol added specifically for cats can be dangerous to dogs.
- Cat food offers fewer dental benefits for dogs than crunchy dog kibble or treats.
- feeding cat food could potentially trigger behavioral problems in some dogs.
- Healthy dog treats or human foods like fresh fruits and veggies offer safer alternatives for a treat.
While an occasional taste of cat food likely won’t harm dogs, it’s not a nutritionally balanced option for canine companions. For the healthiest treat, stick with snacks made just for your dog’s needs. Avoid making a regular habit of sharing kitty’s food. Consult your veterinarian if you have any concerns about your dog’s diet.
Conclusion
Cat food should not be fed as regular treats for dogs. The high fat, protein, and mineral content poses risks of nutritional imbalances and digestive upset over time. Specialized dog treats provide a safer, healthier alternative that won’t compromise your canine’s balanced diet. However, the occasional nibble likely won’t significantly harm your dog. Just don’t make a habit of giving cat food. Ultimately, it’s best to stick to dog-specific formulas and treats tailored to your pup’s unique nutritional requirements. Consult your veterinarian if you have any questions about your dog’s diet, nutrition, or health.
