Pet Cage
Some pets, like dogs and cats can be allowed the run of your house and yard. However many pets require pet cages or tanks. If you tried to keep a pet rat out of a cage it would likely disappear one night into your walls or flooring, never to be seen from again. Other pets need a cage for survival. Reptiles for instance match the temperature of their surroundings, so they require heat lamps and a temperature controlled environment.
For small birds, pet cages are a necessity as well. If you don’t keep finches in a cage, you’re likely to find them one morning nesting inside a hole they dug out of your couch cushions. Larger birds such as parrots do not necessarily require a cage however, they can be perfectly happy with a stand to roost on while sleeping.
When considering a pet cage you should first take a good look at the pet you have. You want a cage that is spacious enough to give your pet room to move around, but with bars tightly spaced enough that the pet won’t reach out and pull things through the bars. Birds will pull paper into the cage and shred it; rodents will chew on anything they can get their mouth on to keep their teeth honed.
While fish and reptiles do not require a cage, they do need a tank. Fish tanks are vital, since they cannot survive outside of them. Since that is where they will be spending the rest of their lives, it’s very important to make sure the tank is big enough to give them space to swim. Reptile tanks are used more for their thermally absorbent nature. Glass reflects heat well, making your heat lamps more effective and giving your lizard or snake a warmer environment.
