Is it normal to think animals think and communicate mentally

Definitely normal. Animals are more intuitive to their surroundings than people are. I got all four of my wisdom teeth out on Friday and my three cats have laid on top of me this entire weekend when they usually sleep at the end of my bed or out on the couch. They know I'm not feeling well, and they're more tolerant of me right now. It's kind of intriguing

I think in many ways humans are the dumbest animal.

Interesting articles. I've run across some other studies as part of my job and have no doubt we've been underestimating the cognitive and communicative ability of animals.

I absolutely believe in what you're saying. I work with hundreds of dogs. Most of them I spend time with on a daily basis. These dogs have personalities and interactions that are more complex than what most people believe. Every dog has their own set of likes and dislikes. They form friendships and even romantic interest (not shown by humping). I noticed that a lot of their communication is subtle and silent but they manage to still communicate very effectively. One of my favorite dogs doesn't like conflict and will warn new dogs of potential problems and basically teaches young dogs about the rules and keeps the room in order all using nearly no vocal communication (and he's not even an alpha male). I've seen these sorts of things in other animals too so I definitely think you have a point.

can animals communicate usin body language and noises?
yep id agree to some degree dependin on the species and individual and familiarity yall gots with em

is they magical telepathic creatures?
nope and yalls gots a heavy dosea confirmation bias

be good to the animals anyways

Can you post some links to these studies?

Sure. I used to think my stuffed animals were alive and had souls and emotions. I thought that they would be sad if I didn't sleep with them or angry and I would feel their wrath!!!

Very interesting

Yeah man, animals can totally do it.

I think that animals communicate mostly with noises and body language. I do believe they can sense the feelings or intentions of other animals just by picking up subtleties. Maybe it can even be telepathy, who knows.

Uhm.. ever had a thought or think of a song and almost instantaneously a family member "takes the words out of your mouth" or start humming that tune of the song you thought of?

Maybe that can be a form of brainwave frequencies being transmitted between the parties involved. So that could probably be how your specific pets just 'get' each other. Scruffles is busy thinking of a Slipknot song and all of a sudden Commodore Fluffyankles starts humming it.

That sense of connection is more prominent between animals, humans, mexicans...who spend a lot of time around each other.

So, yes, I do think that animals, by some means can communicate in a higher manner.

You can't compare canines to dolphins any more than you can compare monkeys to tortoises.
It is a well known fact that dolphins are every bit as intelligent as humans, if not more so. In fact there are some scientists who believe that dolphins are the humans who never left the oceans.
Though dogs do seem to have thought, it is nothing like human thought. Dogs do not have language and therefor cannot think in words as we do. Their communication is more in actions rather than ideas. A wagging tail indicates happiness, ears back and teeth bared indicates anger or fear, etc.
It is a human failing to ascribe human emotions to animals. Animals do not smile or laugh; it just appears so to us. Parrots do not understand the words they say; they just parrot the words.
