According to specialists at ASPCA, enrichment is essential for both cats and dogs of all ages, and keeping their environment as exciting and stimulating as possible will promote a happy and healthy life.

Keeping the inside of your home stimulating and fun will help decrease boredom and decrease potential behavioral issues. The best part? You don't even have to spend money on it. You can just get creative. Just check out their canine and feline DIY enrichment guides.

Many of the toys we see on this list are plushies. Soft stuffed animals are suitable for several reasons but it's good to know which one your pet would get the most fun of. For some cats, the stuffed animal should generally be small enough to carry around. But if your cat wants to "kill" the toy, the stuffed animal should be about the same size as the cat. Bonus tip: toys with legs and a tail seem to be even more attractive to cats.

The same applies to dogs as well. Some pooches like to carry around soft toys. So if your dog sees their toy as a companion, pick one that's small enough to carry too. But other dogs want to shake and "kill" their toys. If that is the case with your little K9-wannabe, choose one that's large enough to prevent accidental swallowing and sturdy enough to withstand the attacks.

To make your pet's toys last longer, rotate them weekly by making only a few toys available at a time. Keep a variety of types easily accessible. However, if your four-legged friend has a favorite toy, you may want to leave it out all the time.
