(This is a review on all the Pet Centers I have ever been in. Most stores in Prague.) Well most pet…read morecenters are pretty horrible to look at when you walk in. Very often overpriced. Most of the time, the in store animals don't have enough space, the right lights, the right food, or the right enclousure (Which includes the right roommates for the enclousure.). A lot of the times, the animals themselves have injuries or are sick. Please don't support these big chain pet stores. The stores don't care about animals.
As a little personal story of mine. Once I actually came inside, I saw a snake that seemed to have an injured face, almost like a cut or an ulcer going up from his/her upper lip to her nostral. Which was probably the most obvious form of sickness/injury I saw. Others were malnourishment, overstocking every single fishtank even with agressive fish, putting (even though the species is usually peaceful) agressive animals in tiny enclousures together, or even having tarantulas or whatever kind of big spider in tiny and very shallow boxes/terrariums, probably so people can see them but that is no excuse for abuse. Overall, it's just not pretty.
So please, do not support these shops with poor care. Go to your local pet shop instead!
