I’ll put my feedback in red.
He’s a veiled chameleon, male, I'm not sure how old he is but he seems to be around 2 months maybe 3, (He's only shed once). I've have him for about a month now.
-Before I realized he had MBD maybe 2 times a week, or when I had to clean or fix his cage. Now that he has MBD I tend to handle him around 4 times a week. Pascal doesnt seem to mind me handling him, though at times he does puff up and hiss at me. At first Pascal had to be fed with a syringe as a two man job, but as he regained his strength I don't have to open his mouth anymore, as I put the syringe close to his mouth and he eats.
-I fed my chameleon crickets and mealworms but i've seen that mealworms arent recommended so i will stop on that. He would usually eat around 4 or 5 crickets in a feeding, (Medium ones) and sometimes he would walk over to his food bowl and eat a couple mealworms.
At his age he should be eating as much as he wants in a 15 minute period. After he’s around 3 mos old, you’ll want to give him around 14-15 feeders daily. As he gets older, you’ll gradually reduce his feedings. I’m attaching the feeder graphic for you. Roaches and silkworms are great additions. I usually feed him after I mist his cage in the morning. I gut load the crickets with bloc choy and kale, as well with apples, sweet potatoes and sometimes mango. I also feed the crickets Repashy Bug burger.
Pretty good. Attaching gutloading graphic too just for guidance.
- I coat the crickets in Repcal calcium No phosphorus and no vitamin D3 for every feeding and Repashy Calcium Plus LoD every 2 weeks.
Good schedule. Did your vet prescribe any liquid calcium?
-I bought a little dripper that is quite useful, I tend to put it at the top of his cage where it drips down. I mist around 4 times a day maybe 5, depending on his humidity and temp for around 30 secs to 1 min.
You could decrease your misting to 2-3 two minute mistings…one early AM and one in the evening. Either a third mid day or use your dripper. I see my chameleon drink water from his dripper, or I will give him water myself and see him drink.
Consider yourself lucky! Many chams (like all of mine) are secret about drinking.
-His feces we're always brown with the gooey coat and white tip. Last time I saw him poop was maybe about a week ago around after his vet visit.
Try to collect a fresh sample and take to the vet to have checked for parasites. You shouldn’t have to make another appointment for that. It was a the same texture, except it looked a little more unraveled, I'm not sure how to explain, and the tip was a little brown. I've been giving lots of water and mist his cage more often.
-I got him from petco, just a baby chameleon
-His enclosure is a 18x12x20 Zilla fresh screen habitat
This is ok for now, but he’s going to be growing fast and will need a minimum 2x2x4’ enclosure. My male uses all of his space and I’m actually going to give him a ’double wide’ soon.
-He has a Zoomed daylight blue reptile lamp 40w, I try to have lights on for 12 hours and no lights for 12 hours. I have a basking red night light, but I've read that they dont need light at night, as it can disturb their sleep schedule.
Colored lights can hurt sensitive cham eyes. You can use an old fashioned incandescent bulb for basking, if you can find one. Halogen works too. LED does not put out the heat. Very important - you need a uvb light. Without correct uvb, his mbd will only worsen. You’ll need a linear T5HO fixture with a 5.0 uvb bulb. Arcadia makes a nice one (similar price as ReptiSun). https://www.pangeareptile.com/store/arcadia-prot5-uvb-kit.html You’ll want it to be as long as your enclosure is wide. As you’ll be needing at least a 24” wide enclosure soon, is better to get that size from now. You will need to suspend your lights, basking and uvb, above your enclosure for now. Besides the little ones liking to screen climb and risking getting burns, you need at least 8-9” of space between your basking area and the uvb light. We don’t want to bake the poor little guy.
- His temperature is usually around 70-80F, he tends to go to his basking spot right under the light bulb.
Basking temp should be 78-80. Most accurate readings are with a digital thermometer with a probe. The lowest overnight tempt can be 65F,
Nice drop for night time. I use imagitarium thermometer and humidity gauges.
- His humidity levels stay at a steady 35-45%
Perfect! and can go up to 50-55% when misting. I use a misting bottle to maintain humidity, I use humidity gauge.
You could get a fogger/humidifier for night time when it’s cool and boost your humidity to 80-100%. It simulates natural hydration.
-At the moment i dont have live plants, just some fake one, which i know they are bad but he likes to hid in them. I will soon get some golden pathos, and i will have to try and fit in his enclosure.
I’m not so sure if the babies eat plants much, but the older chams do. All it takes is one nibble of a fake leaf and he could get impacted. Attaching 2 safe plant graphics for you. Start accumulating them now. I use my fake plants on the outside of my enclosures to provide extra privacy. If funds allow, you may want to splurge on Dragon Ledges which make hanging branches, vines and plants a breeze. https://dragonstrand.com/dragon-ledges/ Some members have made their own.
-His cage is on top of my dresser, like 4 feet off the ground, not near any doors or windows.
Perfect!
-Im from california
So, you do have some corrections/improvements to make. The correct uvb is perhaps the most important one right now and can’t wait. Natural unfiltered sunlight will also help him to recover from mbd if you can take him outside safely for a bit. Just be careful that he doesn’t overheat. I’m in Florida and take my friendly cham outside for only about 5-10 minutes at a time when he wants out of his enclosure. Any longer than that and it just gets too hot for both of us.
Do feel free to ask as many questions as you need. Everything can sound so simple and easy, but when actually making the changes, it can get a bit confusing. I think I covered everything. If I missed anything, hopefully another member will catch it.
Very glad to have you and Pascal here.
