I always found it odd that Mounts and Pets were lumped into the same category in the first place, especially when it comes to smaller homes. Yeah, my inn room might only just about fit one camel in it, but it apparently also can't fit more than a single torchbug or goat.

With Houseguests, I've now noticed the lack of space for "Special Collectibles" in many houses even more than before. Separating the slots and changing the limits based on house size would be lovely.

Also, somewhat on-topic, Pet categorization in the Collectibles (and by extension the housing) menu should be improved. What's the point of having all these categories when eight out of ten pets get lumped into the "Exotic" category, oftentimes completely miscategorizing them (because apparently Atronachs don't count as Daedra and chickens are very exotic animals)?

I agree. In general limits are too low for a lot of houses, more consideration should be given to the actual size of the house, but these special limits are especially heinous. I have been trying to make my Linchal Manor into a working estate, and this has been a major roadblock for me.
