puffer fish? awww! could you post pics?This would be a complex question for me. I keep a variety of pets, from cats and dogs and rabbits to several species of birds, to puffer fish. I love each species in a different way because of the different ways to interact with them. For the most part, I do have a favourite of each species.
For cats, I have four. Two are Sphynx, one is Siamese, and one is a huge old male grey tabby I adopted from a shelter. My favourite is the Siamese, he's the most devoted to me. He cries if I shut him out of a room where I am, and can usually be found curled up on my lap when I'm sitting on the couch. The Sphynx are fine and affectionate, but they have quirky and sometimes irritating habits. The Old Man prefers to be on his own most of the time, he has always been pretty independent.
My two dogs are a Chihuahua and a Chihuahua mix. I love both equally.
Right now I have four rabbits, Zelda (dwarf mix), Stewart (Netherland Dwarf), Rupert (Giant Chinchilla) and Saoirse (Flemish Giant). Right now my favourite is Saoirse. She's the most friendly and interactive of the group. Zelda and Stewart are bonded and prefer each other's company, and Rupert has a shy personality.
Birds: I have a parrotlet, two pairs of button quail, and a whole bunch of budgies. I recently rescued six budgies that were left behind by a former tenant in my apartment building. I bought a huge flight cage for them, which I now called Budgie City. The budgies are my favourite because it's so much fun to watch them in their cage. I tamed the parrotlet but he became very stubborn and bratty, eventually took up biting as his favourite hobby. So now he stays in a big flight cage with all of his toys.
I like my two little puffer fish a lot as well. They are cute and chubby and they swim around like little helicopters.
