Is it problematic/speciesist to have a favourite animal?

Note: It's become clear to me that so far the vegan community on Lemmy (unlike Reddit) is lacking and overrun by non-vegans. So please only answer this if you're actually vegan. I'm seeking a vegan perspective on this.

With that out of the way, is it speciesist to have a favourite animal? Many vegans consider themselves dog 🐕 lovers or cat 🐈 lovers ("ailurophiles") first and foremost, aside from animal lovers (who actually respect animals hence their veganism) in general. Others, like Joey Carbstrong, say that pigs 🐖 are their favourite animal and always have been even since before they went vegan; maybe some saw the movie "Babe" and developed an affection for them, for example. It's understandable. And others like cows 🐄 or chicks 🐥 or lambs 🐑 of course.

But as much as it might be a natural thing to gravitate to a certain species of animal, and "favouritise" them, is that still a form of speciesism? Of course if you're not actually exploiting the animals that aren't your favourite then it's only a mental matter. But is it still wrong even just to view them differentially and prefer or hold more love for some species than others? Loving an individual than another makes sense. But would you love one race of people more than other? Do you say "Greek people are my favourite race" (as a non-Greek person, for sake of example)? If not, and if that would be considered racist, then why is it not speciesist to prefer one species over others, even if just mentally?
