What pets are the easiest and the hardest to take care of?

1. Tardigrades. All you have to do is keep them in a semi moist climate and feed them every couple years.

2.Dogs require a lot of attention and money.

3. Again tardigrades. All you need to do is take some moss, and wash it under a tap and then shake it into a petri dish and as seen in 1, just make sure to feed it very occasionally.

4. Dog.. Having owned a dog for 14 years now, I have calculated with food costs, trips to the vet etc., she has cost me over 20,000 dollars (she had surgery a few times)

5. Puppies require a lot of attention and always are getting sick or hurting themselves

6.Again a tardigrade. They require so little attention you could go away on vacation and not think about them for 5 years and they'd be fine.

7. Dog. My dog sleeps for about 22 hours a day.

8. A puppy because they always are running circles around you and jumping and generally causing a mayhem. They never seem to get tired.

9..Probably a dog when they are younger. They constantly want attention and are always look for mores ways to do so.

10. Probably a cat. They run away for days, even weeks at a time without anyone seeing them and hide and run away from anyone who tries to pet them or even give them food.

Tardigrades are micro-animals for your information, and are common pets that are extremely resilient to everything (they can survive in space)
