Frog growth rate

[acceberbex]

I had some frogspawn that I fished out our pond. I now have several tiny froglets (back and front legs, short stubby tail - less than 2cm big).
I have them in a guinea pig cage ( http://sarniaguineapigrescue.weebly.com/… - the green ramp to the shelf is sitting on 2 bricks to make it less steep and I've put cardboard across the edges to stop them escaping. The top is uncovered (just the bars over it)

And I have just seen a fully grown massive frog in there. The other froglets are still tiny and there weren't any that looked any bigger. Is it possible that this frog has just had a huge growth spurt and I've missed it? Or has it got it through the bars in the top? The cage is right next to our pond but would a fully grown frog really jump on top of a cage and squeeze through the bars?

I am really doubting it's one of mine due to the huge size in comparison to the other froglets (and me still having taddies with just back legs!). It's been hot (UK) like 30 each day for the past 3-4 days and I've been feeding bloodworms and daphnia. Can I really have a fully grown frog that I have not seen at all and totally missed it's growth? I check them daily and none have changed in the last week (more froglets but no bigger). They can only get out onto the bricks either under the shelf (but only just) or onto the shelf (covered in bark to hide under)..so I really don't see how I could have missed it?!

*this is the first successful year I;ve got anything past tadpole stage so I'm really clueless!*

Hello and welcome to FF! Hum... either it got in cage by itself or prankster put it there to mess with you . Would take out because it will probably prey on the smaller froglets. Do you know which frog species is in area or can post pics of froglets to try and identify them?

I think it did get in by itself...I saw a frog in the back garden about 2 days later and the one in my "cage" had vanished! How small can frogs squish down to? (I mean like hamsters can squeeze out through tiny gaps)?

I have no idea. I just fished the frogspawn out the pond and have raised it since (although I now only have 2 froglets I think and some massive taddies but they don't seem to be changing

Frogs can be very agile they can actually get in some pretty tight spaces. They will grow at different rates. The sex of the frog can also be a factor. And a grown frog would definently try to get into that cage to feed on the smaller ones depending on the species of course. they may also morphe at different times as well an american bullfrog tadpole can morphe in a matter of a few weeks but depending on the temp of the water it may take 2 years for them to morph. I have no idea if that has anything to do with the species you have there but it is always something to keep in mind. But from the sound of it, it is pretty warm where you are so they should be morphing pretty quickly and you will have a varity of sizes. They will be on the dinner menu for the larger frogs in your area. Can you take close up picks of the morphed frogs?

Some changed really quickly but I still have several that haven't (although just seen another froglet with his tail but he is as big as those without their tails!)
I doubt they are anything special just being pond frogs from England. Some of the lines may be the surface of the water

I think all frogs are special. Because some researchers state that when my grand kids are my age all frogs may be extinct. They look pretty cool. Keep us posted on your adventures with them. I wanna see one full grown.
