Hello, everyone!
I am going to rebuild my cage to 4x4 grids (quite the upgrade from my 2x4) to house my 2 piggies (and hopefully a 3rd (id prefer to adopt, but you have to remember that getting one from the pet store is also helping it. pet stores usually have terrible living conditions!)) I built a 2 grid high stand for the 2x4 cage to sit on, and even though its sturdy, its starting to sag quite a bit, so the 4x4 will be on the floor. I have 2 other animals in the house: a cat and a dog.
My dog (a "chiweenie" (toy chihuahua/miniature dachshund mix)) is actually petrified of the pigs! I know that all dogs have instincts, but he rarely is around the pigs anyway.
The cat is quite a complicated matter. Again, I am fully aware that even though she is OK with the pigs, she may not be all of the time. My cat is very..."needy." She has to have company around! So when I was on vacation in Florida, I had a friend drop by twice a day to feed the cat and the pigs (the dog was at a dog hotel...he barely lasts 2 hours without us!) and she said every time she showed up she found the cat sitting in the cage. Knowing my cat, it is because she was very lonely and needed company. She has never showed agression or a want to play with the pigs (she actually just walks right by them after a quick glance or sniff during floor time).
OK I appologize for the long explanation. On to my question:
Should the pigs be fine on the floor in a cage without a lid? I just want to do what is best for them. Thank you!
